And, I had a question. I want to write a script which will check content changes in websites send e-mail to a admin whenever there are changes. How many times in a day or how often will this check be performed ? You must look into how to use md5, diff utilities, for web scraping scrapy library is advised. Ideally this script/program should be scalable for say about 1000 websites at a time.. 1000 sites at a time? Wow, that's huge. Scraping that many sites is resource intensive, would need a nice big stable server that can handle the huge data dumps. Fwiw, Scrapy will only dump the data in the json files so check out a little about the database you want to use, the frontend to serve it, a queueing system to scale 1000 sites, etc... Also, some sites instantly ban scrapers. Watch out for that, and goodluck :) This is much more easier than you think. It looks big because you are solving it as a full-scale scraping problem. This is in fact more in the lines of an incremental crawler. Write a simple crawler that keeps track of a few key entrypoint URLs on every site. You can typically get them from the sitemap or from querying google. The crawler can be hand-written or use existing frameworks like pycurl, scrapy etc. 1. When crawling, use a HEAD request to fetch the page. This ensures you only get the headers of the page not the data. Store the metadata of interest to a file - use an MD5 hash of the URL as a unique name and use a two level directory scheme of squid. The fields of interest would be last-modified-time, etag (if any) and content-length. 2. Recrawl at fixed intervals. Before requesting a URL load its metadata from the cache if it exists - Fill in the If-Modified-Since header and put the last-modified-time in there. Also you can optionally add If-None-Match for the etag, if found. 3. If page is not modified, server returns HTTP 304 error. Handle it. Otherwise download the page or do whatever other actions. Update the cache if modified. For 1000 sites, partition the sites into multiple sets and do such incremental crawls frequently. Use random selection to pick up the sites per set. Use random selection of starting URLs to ensure you visit most parts of a site every subsequent crawl. I have written such systems before and still maintain them. It is an interesting area.

Just wondering what is the need for this ? If you are coding in Python in the first place do you really want to go down all the way to assembly code output ? In that case I think you should start off with C rather than Python. CorePy did it but not for microcontrollers P14p (or PyMite) actually creates a python interpreter in C and puts it inside the microcontroller, and its GPL. PyPy as you know is not yet for microcontrollers and only creates assembly when the JIT kicks in. Cython/Pyrex would convert python with type specifications into extension module...but it will not fit into microcontrollers. I am looking for something more simple, i.e. instead of writing C and compiling it to machine instructions...write python (restricted set..may be) and convert it to machine instructions.

Now the next thing is...what is busybox and can I use it in this case on the SBC? and where to find such SBCs Busybox[1] is a single executable that provides the functionality of many of the basic UNIX userspace utilities (like ls etc.) depending on what name it's called with. You can simply symlink ls etc. to busybox and it'll work. It's very useful for embedded situations since you can just drop in a single executable and get all the basic things for free. Any pointers... ? Apropos SBCs, I recently bought a beagle board[2] for someone who was working on a project. It's ARM based and is quite powerful. It has tons of ports you can connect stuff to. I think he booted it with something called Angstrom[3] and then we connected to it via. serial and got a complete environment. It's powerful enough to run a proper small GNU/Linux. I don't think you need busybox and things like that. This is the only one *I* know of. You can order it in Bangalore from Tenet technologies[4] and it costs a little less than 10k.

Hey Shashidhar,
Others may answer your question, I am not going to do that right away.
I'll just offer a few suggestions to clean up your code. If you do that, I
promise to answer your questions:
a. Use os.path.join() to join path components
b. You don't /have/ to read all the lines of the file into a list before
processing it. The pythonic way would be:
with open(filename) as input_file:
for line in input_file.readline():
...do stuff ...
c. You don't need to iterate over lists using numeric indexes. Even if you
/need/ numeric index, use enumerate. So, instead of :
for index in range(len(somelist)):
...do something with somelist[index] ...
OR
...do something with index ...
use something like:
for element in somelist:
...do something with element...
OR
for index, element in enumerate(somelist):
...do something with index or element
d. Don't chain string operations to just match a substring, use regular
expressions. If you /have/ to chain string operations (for instance, to
extract rather than match), chain them only once. So, instead of :
if
all_lines_in_file[line].split(**'-')[1].split(')')[0].split(**')[1].strip()
== true:
...
...
print ZMP value %s % all_lines_in_file[line].split(**
'-')[1].split(')')[0].split(**')[1].strip()
...and more such monstrosities, do either:
stuff_that_interests_me = line.split('-')[1].split(')')**
[0](')[1].strip()
if stuff_that_interests_me == 'true':
or just:
matched = re.search(-\((.*)\), line) # or some such, depending on the
format
if matched:
stuff_that_interests_me = matched.group()
e. If you need one of three options as values of a dict (which I assume
will serve as a config dict), default the config keys to something. So, do:
config = {'MyFirstKey' : 'ASK',
'MyNextKey' : 'ASK',
...
}
for line in all_lines:
...extract stuff_that_interests_me from line...
if 'MyFirstKey' in line:
if stuff_that_interests_me == 'true':
config['MyFirstKey'] = 'ON'
elif stuff_that_interests_me == 'false':
config['MyFirstKey'] = 'OFF'
...
Excellent advise. Just adding 1 more point to this.
Kindly don't post your code here. Please use repositories
like pastebin for them and only post links here.
(I am thinking I should add these guidelines to the welcome
email...)

If some asks a Java or PHP relevant question, will we not treat that as irreverent? Need not be. If the Java or PHP question is generic enough and on a topic that is applicable to Python as well, it could be something worth answering. For example - if there is a question on multithreading in Java, I would answer it here since the Python threading module has a lot of similarity with Java. However, if the question is like Which class in Java to use for byte stream input then I would politely redirect him to a Java forum. After 12+ years of working in a wide number of programming languages from C to Java to Python to PHP and Perl, I keep a very open mind on this topic. This is a Python forum, but languages are inter-related and there is a lot to share and learn. We are not a Python fan forum IMHO but learned folks who chose to mostly center their discussions on Python and related topics. That shouldn't exclude related discussions in other languages, if there is an overlap with aspects of Python. I am sure this list is subscribed by a number of folks whose day job would be coding in languages other than Python.

Thats probably truer for the python and python trained eyes than any other (in other words its both subjective and contextual and a bit to do with syntax). Allow me to illustrate : If I want to double all elements in a list and then increment them by one, here's how I would use a map in python def double(x) : return x * 2 def increment(x) : return x + 1 print map(increment,map(double,range(5))) and here's how I would do it in scala - notice the last (third) line and consider its readability (I'm sure a scala non-novice will offer something even superior) def double(n: Int) = n * 2 def increment(n: Int) = n + 1 println(0 to 4 map double map increment) so readability is often a function of what one's eyes are trained ot read and also the syntactic capabilities in the language This is just the prefix/postfix thing. Yes, prefix style is difficult to read if there are too many nested levels. Look at lisp code for example. Yes, it feel it awkward when I have to do range(len(x)). Unix pipes and chaining methods are postfix. What you are doing in scala is just that. If map was a list method, I could do this: range(0, 4).map(douple).map(increment) And as unix pipe: seq 0 4 | double | increment I also find map much more atomic and portable construct to think in - after all every list comprehension is syntactic sugar around map + filter, and map/reduce/filter are far more omnipresent than list comprehensions. Recently, I was thinking about converting a list comprehension to map/filter calls and It turned out that list comprehensions are more than map+filter. [i * i for i in range(10)] ~ map(lambda i*i, range(10)) [i * i for i in range(10) if i % 2 == 0] ~ map(lambda i*i, filter(lambda i%2 == 0, range(10))) But the situation gets tricky when there are multiple loop items in the list comprehension. Here is a list comprehension to find all Pythagorean triplets below 100. [(x, y, z) for x in range(1, 50) for y in range(x, 100) for z in range(y, 100) if x*x + y*y == z*z] Try converting this into map/filter and you'll understand the difference. +1. IMHO, map/filter/reduce and the inevitable companion lambda were added on to Python when it was still trying to find its identity on where it stood in the pantheon of dynamic typed languages - since it wanted to be everything for everyone it borrowed some of these constructs from Lisp or other functional languages. With addition of list comps, generators etc, these right now stand out like sore thumbs in the language and should be got ridden of at the earliest. Also, using any of the m/f/r trio with lambda is a performance killer. See an earlier post in a different thread for more on this.

Why is map(sqr, range(1, 100)) faster than map(hex, range(1, 100)) Assuming sqr is implemented in python, it should be slower than hex which is implemented in C. Maybe I should have rephrased it like this. - If using anonymous functions, prefer list comps over map. - If using built-in functions (C functions), prefer map over list comps. - If using pythonic user functions, there is nothing much to choose among these two, since the difference is not much. The reason - List comprehensions perform best, if all the calculations are inline within the two square brackets. Hence it scores over map in the lambda use-case but doesn't differ much if the function is declared outside. def f1(): [lambda x: x*x for x in range(100)] ... def f2(): map(lambda x: x*x, range(100)) ... mytimeit.Timeit(f1) '24.80 usec/pass' mytimeit.Timeit(f2) '37.44 usec/pass' The gain is significant.

With addition of list comps, generators etc, these right now stand out like sore thumbs in the language and should be got ridden of at the earliest. I am certain there are contrary opinions, even though the BDFL has weighed in. So yes, python is unlikely to be the playground for these constructs. I find a degree of elegance and utility to these constructs, though it is as well likely that these may seem like sore thumbs to others. I also used to think likewise when I first encountered these functions when I was playing around with Python many years back. However, I think the elegancy is actually a myth and is perhaps a pseudonym for being cryptic. For example, look at these competing solutions for summing the squares of first 10 integers. 1. List comp sum([x*x for x in range(10)]) 285 2. Map sum(map(lambda x: x*x, range(10))) 285 3. Reduce reduce(lambda x,y: x + y*y, range(10)) 285 I dont think there will be much disagreement that the listing is also in the order of decreasing readability. The list comp solution is graspable at one look, the map one takes one step of mental computation and the reduce one takes a few mental hoops to jump through and is utterly confusing to anyone not familiar with list/functional programming. The reduce one is also very error prone. For example, a small mistake such as, reduce(lambda x,y: x*x + y, range(10)) 2818129390158170901506703075470572449397357853477615482257305306043465L Produces a monstrosity instead of the expected answer. Perhaps those with a LISP/functional background find some mathematical elegance with these solutions. But from a pure Python perspective, they lack any elegance whatsoever. Also, using any of the m/f/r trio with lambda is a performance killer. See an earlier post in a different thread for more on this. Its a performance killer only for cPython - its a function of runtime not the construct. cPython is likely to stay a poorly performing runtime for these. I do hope PyPy will fare much better - but that remains to be seen. These constructs also help parallelisation (but only when combined with immutability), and thats a feature python is likely to be therefore unable to implement as far as I can imagine. Is this a big deal - frankly no, since the sweet spot of python is pretty broad. ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers -- --Anand ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers

To be fair here, I think what he is saying is that Kenneth's problem (getting at the particular value) can be solved by using an aptly written regular expression which might be the fastest - not in terms of CPU cycles alone, but in terms of time to code it up - solution. It is not impossible to write a regular expression which will work for bad (invalid) XML as well. Don't forget that a lot of XML/HTML parsers are actually implemented using regular expressions. You can take a look at sgmllib.SGMLParser, htmllib.HTMLParser etc. No complex text processing gets done without some kind of regular expression behind the scenes.

I liked the analogy but don't agree with the second paragraph. It's not only about size. Thanks to the dominance of SQL databases, everyone tends to think of them as the default and use noSQL only if necessary. That needn't be the case. Small (non Google, non Facebook) applications that need to store documents (e.g. a wiki) *might* work better with a noSQL backend than a relational one Hmmm, better in what sense ? By better if you mean the programmer's or maintainer's work is reduced from designing schema, writing SQL to store/retrieve data, basically all the RDBMS stuff vs designing a rather flat key/value store using a Document store (nosql), I am not convinced. Does it really matter in a small-size wiki project whether you are using SQLite to store your data, vs a mongodb that just runs on your machine ? I would rather go for the sqlite solution since, 1. It is the most simplistic RDBMs one can think of. 2. You get the power of SQL, thereby chance of writing adhoc queries in the future. I don't agree with it. One of the basic premises from where the nosql platforms come is that they are trying to solve problems where your data is distributed in a scale that traditional RDBMs would find it difficult to address with sufficient performance. If I use the CAP terminology, nosql is solving the problems of A and P on a large scale while making no promises on the C side. Unless your wiki need to scale to at least 100K nodes or more, I don't see a real technical reason to use document stores apart from relieving you upfront of complex schema design and writing SQL queries. If you mean that is better for you, then we are talking of different problems here. Mileages vary. http://stackoverflow.com/questions/2559411/sql-mysql-vs-nosql-couchdb It might be a cliche, but I kind of feel the current NoSQL movement is simply a case of The grass must be greener on the other side. I don't really follow movements but disagree agree with your general statement. The kinds of data and hardware that people are dealing with have changed and different problems are cropping up. The constraints and requirements have changed as well. New technologies have come up to address these problems and given that we live in these times, it's quite possible that the problems we face might fall into the categories for which these systems have been designed. It's unwise to summarily dismiss document stores out of the box. Also, the transition is not abrupt (SQL yesterday, noSQL today). SQL databases have been used in a semi schemaless fashion e.g. Triple stores[1], Entity-attribute-value model[2] etc. For some kinds of datasets, sound RDMS rules are violated to gain performance. e.g. Denormalisation[3]. These kinds of things indicate that RDBMs systems are not designed to handle certain classes of problems that are cropping up and new solutions have to be sought out. It's an engineering problem. Different situations call for different tools and solutions. I personally tend to ignore the whippersnappers with their SQL suxx0rZ! noSQL roX! outlook and the grumpy SQL advocates with their Get off my lawn! attitude. You might have got me wrong. My point was that there seems to be a trend where programmers and designers choose to implicitly assume that just because their data is expected to scale to gigabytes or terabytes in the future, the right choice upfront is a Document store (I prefer to use this term as against the confusing nosql one), which is not the correct way to do this. I think any complex data storage problem will at the end consist of a mix of Document stores and Relational stores. For example, in the link I quoted the O.P seems to come from that kind of a thinking. Something to do with all the current thinking in terms of cloud and data out there and the fashion to think of SQL as that old thing and Document store as this flashy new thing. Looking at the hardware part of it, RDBMs have been severely limited by current storage technology, i.e platter spinning disks, which is a limiting factor when trying to optimize closer to the metal. SSDs could solve a whole lot of the problems at that level, though now a day's the trend is to blame the poor performance on the DB and think of a document store which scales to millions of nodes, like Digg did for example.

We are archiving a lot of information, some message format very similar to email in structure, through its not an RFC complaint format. Presently we are storing some basic seachable details in a data base, and the physical file is in a SAN box, with the location of file also in the database. It's fine now, but we are expecting the client to generate a few TB of information over the next 2 years. Does this make a good case of using NoSQL. Also I remember someone saying that NOSQL stuff like MongoDB does a miss a document once in a while. Wow, interesting discussion. I missed the crux of it I believe. Anyway here are my 2 cents on this. Document storage, query and retrieval always has 3 aspects - Data consistency, Data availability and Data distribution (partitioning). Traditional RDBMS (aka SQL) Databases focus mainly on the first one, i.e data consistency - hence we got the terms 'ACID' compliant and the like. On top of such structured data which always promise you consistency, they provide a structured query language, aka SQL. In this world, Availability and Partitioning are always add-ons, that painful process the DBM has to perform with DB replication, mirroring, modifying schema for partitioning, Clustered DB etc. The new generation DBs instead chose to focus on the latter two, i.e availability and distribution, while making some assumptions on the consistency part. They are natural evolutions from the data grid or cloud architecture where data is massively striped and scaled on to multiple nodes in multiple data centers thereby lowering your data retrieval latency to the scale of micro seconds. Hence they are a natural fit if you don't mind some inconsistency in data retrieval from say 2 clients across different geographical locations at the same time, but you are more concerned about how quick the data is stored and retrieved. These DBs also choose not to use SQL, hence the NoSQL term. The reason is that they don't need to use SQL since the focus is not so much on queries that span and join across multiple tables as in a fast fetch, given a key There are some problems which fit the NoSQL world and some which fit the the SQL one. If you are bank, you won't dare to dream not having data consistency, since data correctness and atomic transactions are so much essential in the financial world. But a twitter or Google can live with some minor inconsistencies, but they need fast response time, so map/reduce and NoSQL DBs is a natural fit there. So an approximate rule of thumb would be, 1. If your data is highly structured and you have complex queries and your clients expect consistent results, stick to RDBMs. 2. If your data is more like a simple key-value store and you are more worried about query/response times rather than the consistency of the data, perhaps a Document storage (no sql) design is the correct one. To me both these worlds are complimentary to each other. I don't believe in the so-called 'sql' vs 'nosql' wars. That is simply a media hype. --Anand ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers

But personally, I think that it is a very good one/two person project and I would like sprints to be a community event. Like if we can get at least 10 people to work on enhancing/ bug fixing the existing projects (bluebream, django, twisted or python and similar) so that new-comers have an edge in joining the respective project communities, it would have a greater benefit. If we plan or decide upon such an event in the near future, we should take this opportunity extended by PSF. Also, if we plan for Sprints, we should allow remote participation too. (I can participate only remotely for bangpypers these days :) !) Yes, there is a formal procedure for applying for python sprints. It would be nice if we can have a mini meeting or discussion on topics where people in BangPypers are interested to submit proposals on. Proposals need not be on popular platforms such as Django, Twisted etc, it could be for some of these categories also apart from obvious ones such as contributing to Python core and standard library. I am giving a few examples below, which are not very obvious. 1. An unmaintained Python library which is still used by a sizeable number of people which you want to port to Python 3.0 or suggest some improvements as part of a sprint. 2. Improving documentation for an existing Python project. 3. Educational libraries, tools and websites. In short, any problem which is felt reasonably widely as a void in the community or sub-community is good for a sprint application.

That includes darwin (mac os x) and cygwin on windows. But of course not the DOS terminal. Please don't use X like the way you did in the 2nd approach, *nix really can do better than that.

The book is good, but refactoring can be applied in many other contexts too. It has been happening long before the book came out. The big insight in the book is not the refactoring patterns themselves. The big insight is that its possible to make fairly large changes using small steps where the application does not break at any of the intermediate steps. It changes your thinking from I need to rewrite retest to go from A - B, now its like how can I go there in small steps without breaking anything in the middle. Unless you plan to keep rewriting your app everything a change comes along, I do agree that a self respecting developer needs to know refactoring (the concept, not the book) Refactoring myths - - If I write perfect code the first time, then I don't need to refactor: Wrong! Requirements change, and then your perfect code is no longer suitable, so you'll have to go in and change the design before you can implement new functionality. Thats refactoring. - Refactoring means cleaning up bad code: Wrong! See above. - Refactoring is only for OO code: Wrong! You can refactor anything, even imperative of functional programs. I have used refactoring (including some patterns from the book) on C programs. - I have not seen refactoring used on open source projects: Wrong! At least on the django project refactoring occurs _very often_ to support new functionality. When multiple database support was introduced, the ORM design (which only supported single database) was refactored without changing existing functionality. After that the multi-database feature was added. Django has a policy of having unit tests for _all_ functionality, just to support easy refactoring. I'm pretty sure it happens in all large projects. - Refactoring is only for code. Wrong! We recently released a second product which sits along with our first one, and it required completely changing the architecture of the first one - we refactored the architecture to support the new product over 3 months deploying small changes at a time. Architecture changes, server configurations, database structure - everything was changed making small changes every week on a running production system with no downtime - thats refactoring too.

Err... Refactoring _is_ redesigning, that is the whole purpose of refactoring. The difference is that traditional rearchitecting/redesiging is taking down the existing design and rewriting the application with a new design. Refactoring is doing it in such a way that you can go from A - B in small steps without breaking the app at any point. I understand the difference. You mentioned Architecture changes which doesn't belong to re-factoring. In a way, the whole re-writing vs re-factoring thing is a bit blown-up since the answer to the most important question Who throws away an entire piece of code and re-writes it from scratch is Not many, unless the code is highly experimental, a prototype, is a personal project (with not many users), or has hit the critical limit of usability and extensibility in its current state, so that it has to be re-written from scratch.

However refactoring as discussed here is a more of a standardized process using tools and approaches designed for it, with some little buzz added to the mix. Refactoring assumes that the implementation of the code is not closely tied with its interfaces. In other words, it assumes some amount of separation of concerns which will allow to modify the inner guts without changing the external behavior of the code. This may not be true with badly written or maintained systems, which is why many people shudder at the thought of refactoring their code base. In such houses the thinking is, if it works, leave it alone, an attitude that is the exact opposite of the refactor. I think, the thread got a bit digressed.

Your regex is complicated because you are putting all rules
into a single regex. There are different ways to make this shorter.
The best option according to me is to define two regexes, one
for the STD code part and the other for the number part. So in
this case, it will be like,
std=re.compile(r'(^0\d{2,4})')
num=re.compile(r'([1-6]{1}\d{6,8})')
number='080-25936609'
Find out the lengths of the std and number parts.
l1=len(std.findall(number.split('-')[0])[0])
l1
3
l2=len(num.findall(number.split('-')[1])[0])
l2
8
And do the rest in code.
If (((l1==3) and (l2==8)) or ... ):
print 'valid number'
else:
print 'invalid number'
The second option which I don't favor is to split the rule into 3 regexes
instead of ORing them together and then do a simple OR in code.
r1=re.compile(r'(^0\d{2}[-\s]{1}[1-6]{1}\d{7})')
r2=re.compile(r'(^0\d{3}[-\s]{1}[1-6]{1}\d{6})')
r3=re.compile(r'(^0\d{4}[-\s]{1}[1-6]{1}\d{5})')
Then of course,
if (r1.match(num) or r2.match(num) or r3.match(num)):
print 'valid'
else:
print 'invalid'
If you can't use *any* code and absolutely has to do this directly
in regex, revert back to your original one. There is no other way
to do this using the re module.

Let's not conflate this with Open Source/Closed Source etc. Python is the language which has (what in business terms is coined as) the right of first refusal. ie. evaluate something whether it really makes sense in python, and if not in python then start exploring what else. The primary reasons which may encourage me to use a language other than python are : a. Need for raw CPU power. Yes there are a few of such use cases. When purely CPU driven and when you really really need the CPU badly (which is probably less than 5% cases) python performance is really poor. b. Need for high amounts of multithreading even while being largely CPU bound. Yes - both situations can be handled by escaping to C from python, but I would much rather handle these in Java (or languages based on JVM) rather than C unless I am in a very constrained hardware situation. On a separate note I do believe as we start heading towards the 32 core situation (say in 5 yrs time) - there better exist a better solution than the GIL :) I think we should move from the thinking that concurrency = threading and move over to better solutions in languages like Python which have better ways of solving the concurrency problem than actually having to create OS level threads. If you look at it differently, concurrency is the real problem and threading is just one approach to it which is kind of resource intensive and doesn't work great in Python due to the GIL. But instead of GIL bashing, one should look at other approaches to concurrency such as generator based co-operative threading and also look at numerous other concurrency libraries in Python before deciding that going the way of actual threads is his solution. The following article by Michele Simionato tries to drive home the same point. It is a good read, except the parts where he is trying to plug his concurrency library into it :) http://www.artima.com/weblogs/viewpost.jsp?thread=299551 Python should go the direction shown by languages such as Erlang which has true user-space multitasking with light-weight processes. It already has the infrastructure for it with generators etc but support for true multitasking at user level should be part of the language rather than added on by third party libraries. Right now if one decides to explore Python concurrency, the scene is truly confusing and a little scary, since there are too many approaches out there which also share a lot of similarities. Hopefully the futures have something to offer here :) --Anand -- ~noufal http://nibrahim.net.in ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers -- blog: http://blog.dhananjaynene.com twitter: http://twitter.com/dnene ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers -- --Anand ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers

Re: [BangPypers] When *not* to use Python
On Wed, Oct 20, 2010 at 4:57 PM, Noufal Ibrahim nou...@gmail.com wrote: The project management thread highlighted this issue of if it's not in Python, I don't want to use it. Assuming that most of the people here are mostly python enthusiasts or learners, I'm wondering when you would *not* use Python. Let's not conflate this with Open Source/Closed Source etc. I'm just interested in situations where you'd stay away from something *just* because it isn't in Python. The only reason I'd stay away from something like this is if I needed to work on it's code and it was in a language that I wasn't familiar with and didn't have the time to learn. Also, there are plently of situations where I'd jump to a language other than Python at the outset (e.g. for log file parsing, Perl still wins for me). Maybe for rough n dirty use-once-and-throw parsers, but if you want to write reusable parser classes, Python can do an amazing job at it. You should be pretty good at using the re module and if possible have experience writing custom parsers and preferably burnt your fingers trying to understand the HTMLParser module :) I spent like 2 months in HP developing a log file reverse parser application for finding out software install times from the log files. All code in Python. I guess (and hope) they still use it there :) Comments? -- ~noufal http://nibrahim.net.in ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers -- --Anand ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers
