March Madness Challenge - MMC01

I'm going to be part of the March Madness Challenge!

I'm will use Python, because I never used it. So don't expect much, just small little helper programs to learn Python.

The first program is a classic: It loops thru a given folder and prints the name of the files that have the extension you want.

#! /usr/bin/python

import os

import sys

def visit(arg, dirname, names):

os.chdir(dirname)

for name in names:

splitName = os.path.splitext(name)

if (splitName[1] == sys.argv[2]):

print name

def usage():

print 'List all files in given folder with specified extension.'

print 'Use MMC01 Path Extension'

print 'Example MMC01.py . .py'

print '***** MMC01 *****'

if (len(sys.argv) != 3):

usage()

else:

os.path.walk(sys.argv[1], visit, 0)

Possible output:

b$ python mmc01.py

***** MMC01 *****

List all files in given folder with specified extension.

Use MMC01 Path Extension

Example MMC01.py . .py

b$ python mmc01.py . .py

***** MMC01 *****

mmc01.py

Sorry about the format messup. I will figure out how to post code with format in here.
