Is there any way in Python to determine what exceptions a (built-in) function might raise? For example, the documentation (http://docs.python.org/lib/built-in-funcs.html) for the built-in int(s) says nothing about the fact that it might raise a ValueError if s is not a validly formatted int. This is a duplicate of http://stackoverflow...

This isn't as malicious as it sounds, I want to get the current size of their windows, not look at what is in them. The purpose is to figure out that if every other window is fullscreen then I should start up like that too. Or if all the other processes are only 800x600 despite there being a huge resolution then that is probably what t...
Hello, I'm using the mechanize module to execute some web queries from Python. I want my program to be error-resilient and handle all kinds of errors (wrong URLs, 403/404 responsese) gracefully. However, I can't find in mechanize's documentation the errors / exceptions it throws for various errors. I just call it with: self.browser...
I've been working on a very simple crud generator for pylons. I came up with something that inspects SomeClass._sa_class_manager.mapper.c Is it ok to inspect this (or to call methods begining with underscore)? I always kind of assumed this is legal though frowned upon as it relies heavily on the internal structure of a class/object. ...

I have a small web server application I've written in Python that goes and gets some data from a database system and returns it to the user as XML. That part works fine - I can run the Python web server application from the command line and I can have clients connect to it and get data back. At the moment, to run the web server I have to...

How do I iterate over a timespan after days, hours, weeks or months? Something like: for date in foo(from_date, to_date, delta=HOURS): print date Where foo is a function, returning an iterator.

Timsort is an adaptive, stable, natural mergesort. It has supernatural performance on many kinds of partially ordered arrays (less than lg(N!) comparisons needed, and as few as N-1), yet as fast as Python's previous highly tuned samplesort hybrid on random arrays. Have you seen timsort used outside of CPython? Does it ...

A few weeks ago I've run into a site that had tutorials for many languages including Perl, Ruby, Python. The concept was that it basically showed you the code itself of the given language and taught you like that, so the whole tutorial was a great amount of code and some comments in it. The only problem is that I forgot to bookmark it an...
I'm trying to develop an app using turbogears and sqlalchemy. There is already an existing app using kinterbasdb directly under mod_wsgi on the same server. When both apps are used, neither seems to recognize that kinterbasdb is already initialized Is there something non-obvious I am missing about using sqlalchemy and kinterbasdb in sepa...
