Is it possible to create a dictionary from a string value? Something
along these lines (but that works):

dict(mystring)

Yes. It works like a champ. Thanks!

Re: looping through possible combinations of McNuggets packs of 6,9 and 20

Python or Ant
My company is looking at creating a tool to allow us to define and manage a process for each job we run (a typical job may be look on a customers ftp site for a file, download it, decrypt it and load it into our database). We would like something which would allow us to glue together various existing processes we currently use into a single unit with multiple steps. Along the way, this new routine would need to log its progress and be able to report and even handle errors. A coworker has suggested we look at Ant (Another Neat Tool) and, though it looks promising, I have reservations. If I recall correctly, it was intended as a replacement for Make and I worry that we may be trying to force Ant to be something it is not. Also, most of our code base is in Python and I'd really like to stay that way, of possible. Are there any systems out there that will allow me to run multiple programs as one process? We could write our own, of course, and the Twisted package looks like it would be fun to use. Or, is Ant a viable solution to our problem?

Re: Why not enforce four space indentations in version 3.x?
On Jul 10, 2:22 pm, walterbyrd walterb...@iname.com wrote: I believe Guido himself has said that all indentions should be four spaces - no tabs. Since backward compatibility is being thrown away anyway, why not enforce the four space rule? There is a routine in the Scripts directory, reindent.py, that will take your source file(s) and remove tabs, unify the indents to 4- spaces, remove needless characters at the end of lines, etc. IIRC, it was written by Tim Peters. We run all of our source files though before checking them into svn. --greg -- http://mail.python.org/mailman/listinfo/python-list

You get to rub shoulders with other Python programmers who share your interests and all sessions have time for you to ask questions. There is a (modest) cost to attend, but you will get great training as well as class notes. We even feed you lunch and provide snacks during the breaks.

Python and Nagios
Hello all- We have started using Nagios at work to monitor our computer system and have been very happy with the results. We have decided to use it monitor our business processes as well, so I needed to write custom plug-ins and I opted to use Python because I am very comfortable with it. I found an excellent paper by Cameron Laird and Wojciech Kocjan showing the basics (thanks, guys!) and I have written plugins to verify the arrival and departure of files as well as the completion of business processes. We plan to use Nagios to report on file audits and reprocess jobs that have failed because a database or Internet connection burps. We have great plans for Nagios and I intend to submit a paper to next years PyCon showing what we have done. What I would like to know is if there is anything resembling a package to help with plugin deveopment with Python. I have a base class that provides most of the GNU plugin requirements (warning and critical threshold pattern processing, logging requirements, etc) and would like to work on creating something to release for general use, but I don't want to reinvent the wheel. Is there anything close to what I'm suggesting out there? I've looked in the standard places and have not located anything. I will continue to add to my local package and, if I don't hear about a similar effort, will look to create something for the Cheese Shop. If you are interested in helping out, please drop me a line via the list or at gslindstrom via gmail. Thanks, --greg -- http://mail.python.org/mailman/listinfo/python-list

Re: Read a file with open command
AlbaClause wrote: jean-jeanot wrote: snip Ummm, he did not say that your question was stupid. The Zappa quote is included as part of what we refer to as a 'signature'. In the case of Sybren Stuvel's posts to this newsgroup, the Frank Zappa quote is included in every message that he posts. Not just messages that he posts to you. First up, I *like* the Frank Zappa signature quote; it has a George Carlin feel to it and takes a swipe at our overly-protective cultures [side note: I bought an electric heating pad last night that came with instructions not to use it in the bathtub! Well, duh!]. But, can you see where the signature on a response to a tutor list -- where people are already feeling a bit intimidated and/or inadequate and therefore may feel a wee bit stupid -- might be taken the wrong way? I have spent many years teaching mathematics and physics in a classroom setting and have come to realize that, as a teacher, just about anything I say/do can be blown way out of proportion. So I don't use sarcasm or fun little put-downs and I treat every question as if it is the most important matter because, to the student, it is. Do I get tired of answering the same thing over and over? Yes!! Many times I will ask if the student has read the textbook and, if not, I will request they give it a try (much in the same way we ask if they have read any tutorials), but I take Homeric efforts not to offend them and, to that end, modify my behavior in order to teach them mathematics. My point is that this is a wonderful service you tutors provide, but the Zappa signature may not be the best choice for this setting. Most people will read it and get a laugh (as did I), but how many have taken it the way jean-jeanot did and walk away feeling insulted? How many will not post a response expressing their feelings, never post a question again or, worst case, decide Python is not for them? Again, I admire this list and those of you you maintain it. These are just my thoughts. YMMV. --greg -- http://mail.python.org/mailman/listinfo/python-list
Re: do people really complain about significant whitespace?
Carl Banks wrote: Although Python doesn't do this, it is possible to mandate a specific indent (4 spaces, say), or at least a reasonable consistent indent snip I like running reindent.py (found in your Python source directory under Tools/Scripts) which cleans up indentations, trailing whitespace, and other things. We run our entire source directory through reindent before we check it into our library. A very nice routine courtesy of Tim Peters, I believe. --greg -- http://mail.python.org/mailman/listinfo/python-list
Re: do people really complain about significant whitespace?
infidel wrote: Where are they-who-hate-us-for-our-whitespace? Are they really that stupid/petty? Are they really out there at all? They almost sound like a mythical caste of tasteless heathens that we have invented. It just sounds like so much trivial nitpickery that it's hard to believe it's as common as we've come to believe. Some of it may be a reaction from old-timers who remember FORTRAN, where (if memory serves), code had to start in column 16 and code continutations had to be an asterik in column 72 (it's been many years since I've done any work in FORTRAN, but you get the idea) Or it may be a reaction from Assembler, which is also quite column-centric (is Assembler still taught in schools??). But most likely, it's different. It's easier to complain about things than to actually check them out. Recently I had a friend tell me that they absolutely hated a certain tv personality/author. When I asked if they had ever watched the person or read one of their books, they said Why should I? I hate them!!. I think the same attitude comes into play with computer languages. One more thing. I have many friends that love to program Perl. Without bashing the language, I find it ironic when they say There's more than one way to do it but inisit that I should be using Perl while they quote Python as There's only one way to do it though (most) Python coders I know are fairly comforatble dealing with multiple languages. --greg -- http://mail.python.org/mailman/listinfo/python-list
Re: War chest for writing web apps in Python?
Sybren Stuvel wrote: Vincent Delporte enlightened us with: I'm thinking of using Python to build the prototype for a business web appplication. Why just the prototype? I don't know about Vincent, but I once worked in a C++ shop where all other languages were actively discouraged. I would build my prototypes in Python to show proof of concept because I could do it quickly. It was also nice to show project managers so they could verify it was what they wanted us to build before we dedicated a full time effort to development. I recall once prototype I created in wxWindows; when I showed it to my boss he exclaimed That's Python!?. He was amazed because it looked just like the windows apps we developed!
