Try int.
ie.
try:
int_val = int(str_val)
except ValueError:

Now, I said I couldn't think of a way to do it - not that it wasn't
possible :-)
If you don't need you program to be portable you can use extensions -
in this cas

If I had to use python to test C++ code, I'd use the Boost python
library: http://www.boost.org/libs/python/doc/ to expose my C++
classes, and write the unittests in python af
You may also find the cmd module useful, see:

A few trivial corrections, to my own post :-(
tc_sock = socket(socket...
should be
tc_sock = socket.socket(socket...
of course
and, (while I'm here) when I stated that calling connect on an

Fred,
It is quite possible I've misunderstood the problem :-) but have
you tried anything like

tc_remote_port =

remote_tc_host = "172.16.1.3" # say
# udp is the default for DGRAM

Philippe,
Windows file associations are in

Philippe,
You wrote: I wish to associate *.pyc with pythonw.exe
is there some reason why Tools->Folder Options->File Types (from a
Windows Explorer menu) won't work?
You could do it from a cmd prompt with assoc and ftype if you needed to
script it.
All the best,

I'd use the int and chr casts. e.g.,
new_string = ""
a = '012'
new_string += chr(int(a))
Just in case the 012 is an octal code I'll mention that to cast to int
in general you can pass the base, as in int('034',8) or int('AF',16)

Keir.
