find.find

[Gigs_]

import fnmatch, os

def find(pattern, startdir=os.curdir):
matches = []
os.path.walk(startdir, findvisitor, (matches, pattern))
matches.sort()
return matches

def findvisitor((matches, pattern), thisdir, nameshere): #
for name in nameshere:
if fnmatch.fnmatch(name, pattern):
fullpath = os.path.join(thisdir, name)
matches.append(fullpath)

can someone explain why (matches, pattern) is doing in this two funct?

thanks

It's the first argument to `findvisitor()` which is invoked for every
directory level by `os.path.walk()`. `findvisitor()` adds all file names
that match `pattern` to the `matches` list.
