You didn't call md5 twice -- you called it once when you defined the
Phlips naive code:
def file_to_hash(path, m = hashlib.md5()):
happens once, when
def line is executed
If you want separate md5 objects, don't create just one when you create
the function, create one inside the function:
def file_to_hash(path, m = None):
if m is None:
m = hashlib.md5()
You should try the Principle of Learning the Language.
