Anyone know if there is a book for Ironpython in the works? A good knowledge of .NET and Python is enough to get started but just poking around Ironpython homepage it seems like there are some new language features added to handle some quirks with working within the CLR. Although I could be wrong. Thanks -Jake

Hi, String formatting can be used to converting an integer to its octal or hexadecimal form: '307' 'c7' But, can string formatting be used to convert an integer to its binary form ?

I would like to solicit your thoughts and ideas (code can come later) about how you would approach a project idea I just tossed together. I chose this as a testbed for me to play with objects, specifically multiple instances of a few specific objects, and as I thought about it, it raised a lot of questions about how to manage, contain, signal...

Hi! I was told in this NG that string is obsolet. I should use str methods. So, how do I join a list of strings delimited by a given char, let's say ','? Old way:

I want to upgrade to 2.5 but I don't see any unistall instructions anywhere. Robert

I've been trying to find out what the future of Python is with regard to Tk. It seems there are several interfaces that make use of new functionality, including "Tile" and "Ttk". If I want to write a program that will run under the standard Python distribution of the future, what extension module should I work with today? Thanks!

I thought that an iterator was any object that follows the iterator protocol, that is, it has a next() method and an __iter__() method. But I'm having problems writing a class that acts as an iterator. I have: class Parrot(object): def __iter__(self): return self def __init__(self): self.next = self._next()

Please help me think of an example where immutable tuples are essential. It seems that everywhere a tuple is used one could just as easily use a list instead. chris

Hi all, I have been looking at the various programming languages available. I have programed in Basic since I was a teenager and I also have a basic understanding of C, but I want something better. Can anybody tell me the benefits and weaknesses of using Python? -- Your friend,

Hi all, I am running Python 2.5 on Feisty Ubuntu. I came across some code that is substantially slower when in a method than in a function. ################# START SOURCE ############# # The function def readgenome(filehandle): s = ''

If I have a large number of files how would I search for a particular word in all of the files then have the system print out all the lines in those files that have the word that I am looking for. What would have to be different if I wanted to do another program that would search for two words of my choice and then only print out the lines in...

I'm surprised to read this: http://en.wikipedia.org/wiki/Python_3 """Note that while there is no explicit requirement that code be able to run unmodified in both versions, in practice it is quite likely for most code. As of January 2007, it looks like most reasonable code should run quite well under either branch."""

Does anyone else feel that unittesting is too much work? Not in general, just the official unittest module for small to medium sized projects? It seems easier to write some quick methods that are used when needed rather than building a program with integrated unittesting. I see the value of it (the official unittest that is)... especially...

Python is supposed to be readable, but after programming in Python for a while I find my Python programs can be more obfuscated than their C/C ++ counterparts sometimes. Part of the reason is that with heterogeneous lists/tuples at hand, I tend to stuff many things into the list and *assume* a structure of the list or tuple, instead of...

Hi All, I am using pytz.common_timezones to populate the timezone combo box of some user registration form. But as it has so many timezones (around 400), it is a bit confusing to the users. Is there a smaller and more practical set? If not, some suggestions on how to handle the registration form effectively would help me a lot. thanks...

(might not be the right forum for this but...) what is the definition of a highlevel-language? well there isnt one specifically and wikipedia and the like gives just a very general description obv you can say it abstracts away lowlever operations. yes but how?

Hi, I recently read an advice here that one should try to use make and version control system even if you're the only one working on the program. Is that a good advice? How many of you do that? Thanks, -AK
