Rename multiple files in a directory in Python

Use os.rename(src, dst) to rename or move a file or a directory.

$ ls
cheese_cheese_type.bar  cheese_cheese_type.foo
$ python
>>> import os
>>> for filename in os.listdir("."):
...  if filename.startswith("cheese_"):
...    os.rename(filename, filename[7:])
... 
>>> 
$ ls
cheese_type.bar  cheese_type.foo
