[ANN] Leipzig Python User Group - Meeting, February 12, 2013, 08:00 p.m.
=== Leipzig Python User Group === We will meet on Tuesday, February 12 at 8:00 p.m. at the training center of Python Academy in Leipzig, Germany ( http://www.python-academy.com/center/find.html ). Mike Müller (me ;)) will talk about IPython [1] and especially the new IPython notebook. IPython is a greatly enhanced alternative to the interactive Python prompt. The notebook allows to create interactive documents in a browser with markdown, Python code and matplotlib graphics. Even though IPython is traditionally only widely used among scientists, it offers interesting opportunities for all Python users. Everybody who uses Python, plans to do so or is interested in learning more about the language is encouraged to participate. While the meeting language will be mainly German, we will provide English translation if needed. Food and soft drinks are provided. Please send a short confirmation mail to i...@python-academy.de, so we can prepare appropriately. Current information about the meetings are at http://www.python-academy.com/user-group . Mike == Leipzig Python User Group === Wir treffen uns am Dienstag, 12.02.2013 um 20:00 Uhr im Schulungszentrum der Python Academy in Leipzig ( http://www.python-academy.de/Schulungszentrum/anfahrt.html ). Mike Müller (das bin ich ;)) stellt IPython [1] und insbesondere das neue IPython-Notebook vor. IPython bietet eine stark erweiterte Alternative zum interaktiven Python-Prompt. Mit dem neuen Notebook lassen sich im Browser interaktive Dokumente mit Markdown, Python-Code und Matplotlib-Grafiken anlegen. Obwohl IPython vor allem im wissenschaftlichen Umfeld verbreitet ist, bietet es interessante Möglichkeiten für alle Python-Nutzer. Weitere Infos: http://www.python-academy.de/User-Group/index.html Willkommen ist jeder, der Interesse an Python hat, die Sprache bereits nutzt oder nutzen möchte. Für das leibliche Wohl wird gesorgt. Eine Anmeldung unter i...@python-academy.de wäre nett, damit wir genug Essen besorgen können. Aktuelle Informationen zu den Treffen sind unter http://www.python-academy.de/User-Group zu finden.

Can you help me???
Are you traveling abroad on holiday??? Does the resort have enough information on the internet??? Would you like to ask local people information about attractions, good places to eat, nice places, that is, just about anything??? For this site, I have asked people around the world to join and tell the tourists information about their own country / city. Similarly, when they themselves are traveling somewhere, they can get here also interesting information about the destination. A similar service has not to my knowledge found on the internet and I would hope that you decide to join as a free member and you will help other people to make their holiday a successful :) And I also hope that if you are a self-help / information requirements, hopefully my site will also help you http://theworldismy.webs.com/ -- http://mail.python.org/mailman/listinfo/python-list
Coercing one object to type of another
Hi
Inside a function i get a two arguments, say arg1 and arg2, how can i convert
arg2 to same type as arg1 ?
I dont know type of arg1 or arg2 for that matter, I just want to convert arg2
to type of arg1 if possible and handle the exception if raised.
Also:
int('2')
2
float('2.0')
2.0
coerce(2,2.0)
(2.0,2.0)
but coerce('2',2) fails.If int('2') equals 2, why should it fail ?

You can get the type of any object, and call that:
def coerce(changeme,tothis):
return type(tothis)(changeme)

You probably want str.translate(): s = x.translate(string.maketrans(,),string.punctuation) You'll then want to print s, rather than x, to see the difference. Note that it's a little different in Python 3, and you would instead use: s = x.translate(str.maketrans(,,string.punctuation)) ChrisA -- http://mail.python.org/mailman/listinfo/python-list
Python3 curses behavior
Hello. I found strange behavior of curses module, that i can't understand. I initialize screen with curses.initscr(), then i create subwin of screen with screen.subwin(my_subwin_sizes). After that i fill subwin with my_char in for-loop. On last char in last line subwin.addch() raises exception. This is my problem. Why? How to fix it?

well it will always return me this:
type 'str'
what i want is if i know arg1 is of string type(and it can be of any type, say
list, int,float) and arg2 is of any type, how can i convert it to type of arg1,
if arg1='hello world', type(arg1).__name__ will give me 'str', can i use this
to convert my arg2 to this type, w/o resorting to if-elif conditions as there
will be too many if-elif-else and it doesn really sounds a great idea !

That doesn't necessarily mean it has to return bytes, though. It's taking binary data and producing something that's plausibly either bytes or str. It's human-readable and would definitely make sense to be str (for instance, hex() returns a str), so imo this should be made very clear in the docs. Maybe: Return the hexadecimal representation of the binary data. Every byte of data is converted into two bytes with the corresponding hex representation in ASCII. or somesuch?

Oh, okay. Then switch the order of the arguments in what I posted: def coerce(target,convertme): return type(target)(convertme) You don't need to worry about the actual name of the type. It's telling you that it's type 'str'; that's an actual callable object (the same as the builtin name str, in this case). You can then call that to coerce the other argument to that type.

Hi
Inside a function i get a two arguments, say arg1 and arg2, how can i

handle the exception if raised.
How do you propose to handle the exception?
If arg1 is a dict, and arg2 is an int, what do you think should happen?
convert({}, 45)
= returns what?
If arg1 is a HTTP connection object, and arg2 is a function object, what do
you think should happen?
import urllib2
conn = urllib2.urlopen(http://www.python.com/;)
convert(conn, lambda x: len(x) + 1)
= returns what?
You cannot convert arbitrary objects of one type into some other arbitrary
type, it simply doesn't make sense. So first of all you need to decide:
- what kinds of objects do you care about?
- when given some other kind of object, how do you propose to deal with it?
The usual answer to the second question is raise an exception.
Also:
int('2')
2
float('2.0')
2.0
coerce(2,2.0)
(2.0,2.0)
but coerce('2',2) fails.If int('2') equals 2, why should it fail ?
Because '2' is a string, not a number, and coerce only operates on numbers.
What would you expect coerce(three, 2) to return? How about
coerce(apple, 2)?
Why do you think you need coerce? What are you actually trying to
accomplish? If you have two numbers, normally you would just do arithmetic
on them and let Python do any coercion needed. And if you have a number and
something else, you can't magically turn non-numbers into numbers.

For example, when embedded in a game, lua is used as a scripting language to automate and extend the game in certain ways, by exposing game objects to the lua engine and allowing interpreted lua code to manipulate (script) them. Javascript is the same thing in other programs. But whether you call javascript a scripting language in firefox, or something much more (as it's actualy required for firefox to function at all), is a matter of personal preference really.

I don't understand. Wouldn't freezing an array (list) result in a

Having a convenient literal notation for every basic type is extremely
handy. You can work with integers 1, 2, 3, or floats 1.0, 2.0, 3.0. C
gives you those. In Python, you can work with lists, too, and C
doesn't give you those (you have array *initializer* syntax, but
that's not the same thing). It's perfectly plausible to dereference a
literal:
dow = [Sun, Mon, Tue, Wed, Thu, Fri, Sat][day%7]
Of course, it's perfectly plausible to do that with a function, too.
You could define something like this:
def agg(*args): return args
dow = agg(Sun, Mon, Tue, Wed, Thu, Fri, Sat)[day%7]
But the question is, why? Why call a function when the interpreter can
do the work directly at compile stage? There's absolutely no value in
forcing things to be done at run-time.

Actually, that's not a declaration, that's an assignment; and in Pike,

were to declare it in Pike, it would be:
array(array(string)) nested_list;
Though the part inside the parens can be omitted, in which case the
array can contain anything, rather than being restricted to strings.
In actual fact, Rick, despite your complaints about the syntax, it's
able to achieve exactly what you were thinking Python should do:
declare an array/list that contains only numbers.

[...] Of course someone could probably find a legitimate reason to apply a sum method to non-numeric values; if so, then inherit from NumericSequence and create your custom type! Are you aware that the approach you're advocating here is bad OOP design? If you declare a class NumericSequence with the property that it contains only numeric types, and then you declare a subclass NonnumericSequence that does not share that property, then guess what? You've just violated the Liskov Substitution Principle. I totally agree! Really, no sarcasm here O:-) Not only because we would be attempting to bend a numeric type into something it is not, but even more foolishly because the very method we hope to gain (sum) would need to be completely re-written anyway. I must have lost myself in the rant because that was a foolish thing to say. Thanks for pointing this out. The goal you're trying to achieve here is nonsensical anyway. Ask yourself what the semantic meaning of the sum() function is, what purpose it is meant to serve. My answer: it is the reduction of the addition operator. I think that for Numeric Types your answer is spot on! And i'll bet if we ruminated long enough we could probably find a few more transformations of the word sum into unique contexts. But i digress, we'll have to save that synergy for a time when you are buying the beer! ;-) The implication of this is that the input type of the sum() function is not numbers, but rather things that can be added. Indeed. Contrary to what a few folks have stated in this thread, if two different objects have methods named sum, that does NOT mean that we have broken the fine principles of code reuse, no. Why? Because two methods named sum can contain completely different code! Yes, i know that's difficult for some to believe, but it's the truth! Consider a sum method of a Numeric Type compared to the sum method of a Sequence Type. Not only is the algorithm different, but the result is different. Summing N numerics requires utilizing the strict rules of mathematical addition, keeping a running total, and returning a type (Integer) that is different from the input type, whereas summing sequences requires expanding the first sequence with the values of the second sequence (all whilst maintaining linear order) and returning a new instance of the same type (f.e. list). Of course you could write a single monolithic function that can operate on multiple types transparently (*cough* saum!) however: * Nobody can predict the future (at least not yet) so you will eventually encounter a new type that breaks the god @#$% function. * Your language will rely on magic, thereby confusing it's users, with well, magic! * But most disappointing of all: you will break the accepted OOP convention of encapsulation, whereby the object /itself/ should operate on the data, not some outside god @#$% function! But let's dig a little deeper here so we might understand /why/ encapsulation is /so/ gawd @#$%ed important to OOP. Why do we prefer objects to operate on their own data rather than some magical-all-knowing-god-like-creature-from-another-planet-who-thinks-his-bowel-movements-smell-like-bakery-fresh-cinnamon-rolls? Is it because we want objects to feel a sense of belonging or importance? ...OF COURSE NOT! Objects neither think nor feel! We employ encapsulation because by doing so we keep all the relevant code under one class, one module, one package. By doing so we create a hierarchy; and since hierarchies are much easier to search than random sequences, we will thank ourselves later! If you want a fine example of this consider a list and a dict object. If you want to find a value in a list you are forced to search the entire list item-by-item until you find a match; there are NO shortcuts here! However, when we have data in a dict all we need is a key, and voila!, we have a direct path to the item! Same applies to code. RR: GOOD paradigms solve problems when /writing/ code, GREAT paradigms solve problems when writing and /maintaining/ code! That includes numbers, but since I see from your proposed class hierarchy that you are retaining the __add__ method on sequences, it also includes sequences. Are you really going to tell the user that (1, 2, 3) + (4, 5, 6) is perfectly fine, but that the semantic equivalent sum([(1, 2, 3), (4, 5, 6)]) is nonsense? Yes.

[issue17157] issubclass() should accept iterables in 2nd arg
Franck Michea added the comment: I am neutral on this too, it just felt odd and this is why the question raised. Yesterday I tried to add sequences and iterables (only to issubclass but indeed it would need better testing and all) and came to a problem with sequences. The current implementation authorizes (A, (B, (C, D))) (why?) so issubclass is recursive, but if we add sequences, they could create infinite recursions if seq[0] == seq (it's the case for strings for example, where 'a' is still a sequence and 'a'[0] == 'a'). So I don't know if it's really interesting. Anyone can use tuple() on an iterable to build its tuple value, though the value is built in memory. It basically just felt odd to take only tuples but I don't know. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17157 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17170] string replace is too slow
New submission from Guido van Rossum:
I'm trying to speed up a web template engine and I find that the code needs to
do a lot of string replacements of this form:
name = name.replace('_', '-')
Characteristics of the data: the names are relatively short (1-10 characters
usually), and the majority don't contain a '_' at all.
For this combination I've found that the following idiom is significantly
faster:
if '_' in name:
name = name.replace('_', '-')
I'd hate for that idiom to become popular. I looked at the code (in the
default branch) briefly, but it is already optimized for this case. So I am at
a bit of a loss to explain the speed difference...
Some timeit experiments:
bash-3.2$ ./python.exe -m timeit -s a = 'hundred' 'x' in a
./python.exe -m timeit -s a = 'hundred' 'x' in a
bash-3.2$ ./python.exe -m timeit -s a = 'hundred' a.replace('x', 'y')
./python.exe -m timeit -s a = 'hundred' a.replace('x', 'y')
bash-3.2$ ./python.exe -m timeit -s a = 'hundred' if 'x' in a:
a.replace('x', 'y')
./python.exe -m timeit -s a = 'hundred' if 'x' in a: a.replace('x', 'y')
bash-3.2$ ./python.exe -m timeit -s a = 'hunxred' a.replace('x', 'y')
./python.exe -m timeit -s a = 'hunxred' a.replace('x', 'y')
bash-3.2$ ./python.exe -m timeit -s a = 'hunxred' if 'x' in a:
a.replace('x', 'y')
./python.exe -m timeit -s a = 'hunxred' if 'x' in a: a.replace('x', 'y')

[issue17170] string replace is too slow
Antoine Pitrou added the comment:
Characteristics of the data: the names are relatively short (1-10
characters usually)
$ ./python -m timeit -s a = 'hundred' 'x' in a
1000 loops, best of 3: 0.0431 usec per loop
$ ./python -m timeit -s a = 'hundred' a.find('x')
100 loops, best of 3: 0.206 usec per loop
$ ./python -m timeit -s a = 'hundred' a.replace('x', 'y')
1000 loops, best of 3: 0.198 usec per loop
Basically, it's simply the overhead of method calls over operator calls. You
only see it because the strings are very short, and therefore the cost of
finding / replacing is tiny.

[issue17170] string method lookup is too slow
Guido van Rossum added the comment:
Hm, you seem to be right. Changing the bug title.
So, can we speed up method lookup? It's a shame that I have to start promoting
this ugly idiom. There's a similar issue where s[:5]=='abcde' is faster than
s.startswith('abcde'):
./python.exe -m timeit -s a = 'hundred' a.startswith('foo')
100 loops, best of 3: 0.281 usec per loop
./python.exe -m timeit -s a = 'hundred' a[:3] == 'foo'

There are two overheads: an attribute lookup and a function call.

$ ./python -m timeit -s a = 'hundred' a.__contains__

Time of a.__contains__('x') is greater than the sum of times of

[issue17173] uses of locale-dependent ctype functions
New submission from Antoine Pitrou:
Grepping through the code reveals we are still using a number of
locale-dependent C library functions:
Python/mystrtoul.c:102:while (*str isspace(Py_CHARMASK(*str)))
Python/mystrtoul.c:141:while (isspace(Py_CHARMASK(*str)))
Python/mystrtoul.c:269:while (*str isspace(Py_CHARMASK(*str)))
Python/formatter_unicode.c:404:while (posend
isdigit(PyUnicode_READ_CHAR(s, pos)))
Python/ast.c:3764:if (isalpha(quote)) {
Python/dynload_aix.c:144:while (isdigit(Py_CHARMASK(*message[i])))
message[i]++ ;
Objects/longobject.c:2011:while (*str != '\0' isspace(Py_CHARMASK(*str)))
Objects/longobject.c:2255:while (*str isspace(Py_CHARMASK(*str)))
Modules/getaddrinfo.c:228:if (! isdigit(*q))
Modules/_sre.c:153:#define SRE_LOC_IS_DIGIT(ch) (!((ch) ~255) ? isdigit((ch))
: 0)
Modules/_sre.c:154:#define SRE_LOC_IS_SPACE(ch) (!((ch) ~255) ? isspace((ch))
: 0)
Modules/_sre.c:156:#define SRE_LOC_IS_ALNUM(ch) (!((ch) ~255) ? isalnum((ch))
: 0)
Modules/binascii.c:1138:if (isdigit(c))
Modules/_decimal/libmpdec/io.c:153:if (!isdigit((uchar)*s))
Modules/_decimal/libmpdec/io.c:157:if
(!isdigit((uchar)*(s+1)))
Modules/_decimal/libmpdec/io.c:159:
isdigit((uchar)*(s+2
Modules/_decimal/libmpdec/io.c:185:while (isdigit((uchar)*s))
Modules/_decimal/libmpdec/io.c:825:if (isdigit((uchar)*cp)) {
Modules/_decimal/libmpdec/io.c:847:if (!isdigit((uchar)*cp)) {
Modules/_decimal/libmpdec/io.c:1087:assert(isdigit((uchar)*dp));
Modules/_decimal/libmpdec/io.c:1089:while (isdigit((uchar)*dp)) {
Modules/_decimal/libmpdec/io.c:1244:if (isupper((uchar)type)) {
Modules/_struct.c:1273:if (isspace(Py_CHARMASK(c)))
Modules/_struct.c:1338:if (isspace(Py_CHARMASK(c)))
Include/pyctype.h has locale-agnostic counterpart (a bit faster probably, too).

[issue17173] uses of locale-dependent ctype functions
Raymond Hettinger added the comment: +1 for fixing this everywhere. -- nosy: +rhettinger ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17173 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue17170] string method lookup is too slow
Antoine Pitrou added the comment: Here is a patch yielding a decent speedup (~ 40%) on PyArg_ParseTuple itself. More generally though, this would be improved by precompiling some of the information (like Argument Clinic does, perhaps). (note: PyArg_ParseTupleAndKeywords is a completely separate implementation...) -- keywords: +patch Added file: http://bugs.python.org/file29021/getargs_freelist.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17170 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
