Re: IDE for Python

I think many python developers don't need such an IDE actually. Just like Ruby guys, they use a powerful editor, for example, Textmate, instead of all-in-one IDE. It's quick and direct. On 8/21/07, Joel Andres Granados <[EMAIL PROTECTED]> wrote: > Hello list: > > I have tried various times to use

Re: way to define static method

Thanks a lot. Because I found a solution about static method from http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/52304 And that's a little bit difficult to understand. # direct, naive approach -- doesn't work...: class Class1: def static1(name): print "Hello",name # ...but no

way to define static method

I think Python uses a very strange way to define static method in a class. Why not make it like this? class MyClass: def my_static_method(self): # self should be None as it's a static method # just ignore self I'm a newcomer so maybe it's quite naive. But I just wonder why it

socket on cygwin python

I've installed cygwin with latest python 2.5.1, but it seems that the socket lib file do NOT support IPv6(cygwin\lib\python2.5\lib-dynload \_socket.dll), what can I do if I want to use IPv6? Thanks -- http://mail.python.org/mailman/listinfo/python-list

I've been trying to develop some numerical codes with python, however got disappointed. A very simple test, a = 1.0 for i in range(1000): for j in range(1000): a = a+1 unfortunately, it took 4.5 seconds to finish(my machines is fine. P4 3.0G, 1G RAM, it varies according to machi
