Re: [Tutor] exit handler for C extension module

I found what I was after, right after I posted to this list. It's Py_AtExit. I'm accessing an old, unsupported database using it's C API. I've tried using Cython but found it hard to get my head around and I'm finding it somewhat easier to just write by hand. On Mon, Jan 18, 2010 at 6:40 PM, Stefa

[Tutor] exit handler for C extension module

Hi, So I've got a class X with instance variables a, b, c. Is there any way of creating a dictionary of these instance variables besides the no-brainer way of doing dictionary = {'a' : X.a, 'b' : X.b, 'c' : X.c} ? --Shuying ___ Tutor maillist - Tutor@

Re: [Tutor] I'm puzzled

I'm guessing when you did that, you got something like an IndexError. That's because you didn't check the length of "a" from raw_input and accessed a nonexistent array element (a string is an array of characters). So if you changed the line: elif a[0] == '-' and a[1:].isdigit(): to : elif len(a) >

Re: [Tutor] a class knowing its self

Re: [Tutor] CGIXMLRPCRequestHandler doesn't actually work, does it?

I'm not sure what you're trying to do. But I run cgi scripts and make xmlrpc requests with xmlrpclib with a connection with xmlrpclib.Server(server_uri), though I'm only doing this client side. I'm not running the server as cgi. On 6/23/05, Ron Phillips <[EMAIL PROTECTED]> wrote: > > I believe I

Hi tutors, I've got an external program that I'm calling from python with os.popen. The problem is that I need to pass this program an arbitrary body of text. I've tried escaping characters before passing it as input but the shell still expands out certain characters. I noticed with python2.4. How
