Hi - I'd really like to have access to Python 2.6 to try something
out. It needs to be on Linux/Unix machine. I don't mind paying but
whichever way I turn I find Python 2.4 is the standard installation.
Anyone know of anyone who offers this out of the box ? Or got any
smart way of achieving it ?

Hello,
According to my experience and from what I've read in other threads,
subprocess isn't easy to use for interactive tasks. I don't really
know, but maybe it wasn't even designed for that at all.
On the other hand, pexpect seems to work fine for interactive use and

I am sending base64 encoded data as the content over http using
urllib2 urlopen. When I receive the data and attempt to decode it, I

Can some explain to me what is wrong? I have included the dcObject.py
