How to filter files (with known type) from os.walk?

Question

I have list from os.walk. But I want to exclude some directories and files. I know how to do it with directories:

for root, dirs, files in os.wa         


        

Answer 1

Another solution would be to use the functions from fnmatch module:

def MatchesExtensions(name,extensions=["*.dat", "*.txt", "*.whatever"]):
  for pattern in extensions:
    if fnmatch.fnmatch(pattern):
      return True
  return False

This way you avoid all the hassle with upper/lower case extension. This means you don't need to convert to lower/upper when having to match *.JPEG, *.jpeg, *.JPeg, *.Jpeg
