Cool! I like your attitude ;)
Others have given you a good start with os. In case you don't know os
has a great many path manipulation methods. Always try to use them so
you can insulate yourself from cross platform path nightmares.
A few of the highlights are:
### split a path
py> parts = os.path.split(r'c:\windows\media\ding.wav')
py> print parts
('c:\\windows\\media', 'ding.wav')
### join a path and part and do it right on any platform
py> path = os.path.join('c:\\windows\\media', 'ding.wav')
'c:\\windows\\media\\ding.wav'
### get basename of the file
py> base = os.path.basename('c:\\windows\\media\\ding.wav')
py> print base
'ding.wav'
Plus many more, be sure to study the os module if you are doing any
path manipulations.
Ok and now for something sorta different( alright, I was really bored )
. def glob_dir(dir):
. """Return a list of *.py* (.py, .pyc, .pyo, .pyw)
. files from a given directory.
. """
. import glob, os
. # Get a list of files that match *.py*
. GLOB_PATTERN = os.path.join(dir, "*.[p][y]*")
. pathlist = glob.glob(GLOB_PATTERN)
. return pathlist
.
. def list_dir(dir):
. ''' Another way to filter a dir '''
. import os
. pathlist = os.listdir(dir)
. # Now filter out all but py and pyw
. filterlist = [x for x in pathlist
. if x.endswith('.py')
. or x.endswith('.pyw')]
. return filterlist
