Fw: Python vs. Ruby (and os.path.walk)

As seen on comp.lang.python…

I’m trying to settle on Ruby or Python as my scripting language of
choice. There are some features of Ruby that I like, but I lean toward

Python since by day I’m a C++ programmer and Python seems more natural

to me. Unfortunately, in my first side by side test I discovered a
huge performance difference (at least for what I wanted to do). I
need a simple program that can clean out some tool generated source
code. I’m recursively searching 100’s (probably close to or slightly
over a 1000) directories searching for certain file extensions (*_i.c,

_p.c,.thi, *.thl) and then removing them. The Ruby version runs in
about 20-30 seconds. The Python version takes 2-3 minutes! My feeling
is that it’s probably just the os.path.walk library routine is slow
(only on NT, haven’t tried on Linux. Maybe that’s a good sanity
check.). So before I dig into the code to determine why it’s so slow
I’d like to know if others experience slowness with Python overall,
just the os.path.walk routine, only the NT version.

I’ll probably need to do lots of directory searching in future
scripts, so I’d like that to be reasonably fast. Granted I could write

my own extension, or maybe call the Win32 functions directly since the

code does not need to be portable, but I’d rather not do that.
