import filecmp
filecmp.cmp("c:/testFolder1/test1.txt", "c:/testFolder1/test2.txt")

Case 2: 
Compare two directories

Example:

import filecmp
cmp = filecmp.dircmp('c:/testFolder1/', 'c:/testFolder2/')

# print out result
cmp.report()

# get the first directory
cmp.left

# get the second directory
cmp.right

# get the contents underneath the first directory
cmp.left_list

# get the contents underneath the second directory
cmp.right_list

# get the files or subdirectories in both directories.
