It does. What you have to understand here is that in your script, B
being in the global (read : module) scope, it doesnt goes out of scope
before the script's execution's done. By that time, it's too late to do
anything with stdin/stdout/stderr.
Just add this to the script:
b = B()
print "in foo"

Absolutely not. The only times I use del is when I want to cleanup a
namespace from temp vars no longer used (usually a module's namespace
with some hairy tricks at load time).
python -c "print '@'.join(['.'.join([w[::-1] for w in p.split('.')]) for
p in 'onurb at xiludom.gro'.split('@')])"
