Deleting files by type in Python on Windows

Question

I know how to delete single files, however I am lost in my implementation of how to delete all files in a directory of one type.

Say the directory is \\myfolder

Answer 1

Here ya go:

import os

# Return all files in dir, and all its subdirectories, ending in pattern
def gen_files(dir, pattern):
   for dirname, subdirs, files in os.walk(dir):
      for f in files:
         if f.endswith(pattern):
            yield os.path.join(dirname, f)


# Remove all files in the current dir matching *.config
for f in gen_files('.', '.config'):
   os.remove(f)

Note also that gen_files can be easily rewritten to accept a tuple of patterns, since str.endswith accepts a tuple
