This article describes the method of Python using checksum to calculate whether files are the same. Share it for your reference. The details are as follows:

Suppose there are 2 binary files (, ), use checksum to check whether the content is the same

# coding: utf8
# Python2.6.2
import md5
with open('', 'rb') as f:
  s = (()).hexdigest()
with open('', 'rb') as f:
  ss = (()).hexdigest()
print repr(s), len(s)
print repr(ss), len(ss)

I hope this article will be helpful to everyone's Python programming.
