hi, I have a very basic problem. I am learning my first steps with python & scripting in general and so even this makes me wonder: I want to read & write lines to new file: ifile=open("C:\Python24\OtsakkeillaSPSS.csv", "r") ofile = open("C:\Python24\OtsakkeillaSPSSout.csv", "w") #read first line with headers line1 = ifile.readline()...

Pythons installed under WinXP have dirs like DLLs, DOC, include, etc. but python (2.5) installed with cygwin is a bare python.exe. My motivation for asking is that 'things' under XP don't seem to be finding 'other things' under cygwin and vice versa, I want to start developing with Qt, I like shells, and I do not like MS; I thought if I...

In my application, I have two classes: a logger that actually logs to the database and a dummy logger that does nothing (used when logging is disabled).

Should it be possible for gc.get_referrers(obj) to return an empty list for an object, but the object still be accessible through a weak reference? If so how would I start trying to identify the cause for this object not being garbage collected? Edit: I'm not sure exactly how a code sample would help in this case - there's obviously a ...

I like the options offered by the _ast module, it's really powerful. Is there a way of getting the full AST from it? For example, if I get the AST of the following code : import os os.listdir(".") by using : ast = compile(source_string,"<string>","exec",_ast.PyCF_ONLY_AST) the body of the ast object will have two elements, an i...

This is a very newbie question and i will probably get downvoted for it, but i quite honestly couldn't find the answer after at least an hour googling. I learned how to slice strings based on "exact locations" where you have to know exactly where the word ends. But i did not find any article that explained how do it on "non static" strin...
I'd like to use a number with a decimal point in a Django URL pattern but I'm not sure whether it's actually possible (I'm not a regex expert). Here's what I want to use for URLs: /item/value/0.01 /item/value/0.05 Those URLs would show items valued at $0.01 or $0.05. Sure, I could take the easy way out and pass the value in cents so...
I'm trying to code a simple genetic programming utility in python. But right now I'm stuck at the crossover/mate function for my trees. The trees are built by nested lists and look something like this: # f = internal node (a function), c = leaf node (a constant) tree1 = [f, [f, [f, c, c], [f, c, c]], [f, [f, c, c], [f, c, c]]] tree2 = [...
I'm using python Textile to store markup in the database. I would like to yield the following HTML snippet: (<em>asdf</em>) The obvious doesn't get encoded: (_asdf_) -> <p>(_asdf_)</p> The following works, but yields an ugly space: ( _asdf_) -> <p>( <em>asdf</em>) Am I missing something obvious or is this just not possi...
The Django framework easily handles redirecting when a user fails to log in properly. However, this redirection goes to a separate login page. I can set the template to be the same as the page I logged in on, but none of my other objects exist in the new page. For example, I have a front page that shows a bunch of news articles. On the ...
When packaging a Python package with a setup.py that uses the setuptools: from setuptools import setup ... the source distribution created by: python setup.py sdist not only includes, as usual, the files specified in MANIFEST.in, but it also, gratuitously, includes all of the files that Subversion lists as being version controlled ...
As far as I know, for a new request coming from a webapp, you need to reload the page to process and respond to that request. For example, if you want to show a comment on a post, you need to reload the page, process the comment, and then show it. What I want, however, is I want to be able to add comments (something like facebook, wh...
