I think jeff gave the most succint advice as to your question. You
should consider your problem carefully and decide if that is what you
really need. And when in doubt consult the 'documentation.'

I wouldn't automatically assume that recursing the directories with a Python
script that calls a C program for each file is faster than doing the
processing in Python. Fo

Well, there's several different ways of using C and Python together, so

Hi Brad
Not that I'm an expert but note:
1. If you already know C, fair enough. You should know what you are
getting into then. I sure as heck don't know it very well at all and I'm
not gonna make that time investment now. MAYBE if I really really needed
the extra speed (but this seems to

You should probably only expect C to run circles around the same
operations when those operations implemented entirely in Python. In the
specific (trivial) example given, I wouldn't expect Python to be much

I would expect C to run circles around the same operation under Python. As
a general rule of thumb, you should use C for time cirtical operations
(computer time, that is), and use Python for human time critical situations
(you can get a program developed much faster).

you could invoke a compi

It is like the difference between Batman and Ever.
