在 Python 中，有没有比较简洁的方法来比较两个文本文件的内容是否相同?

I don't care what the differences are. I just want to know whether the contents are different.

解决方案

低级方式:

from __future__ import with_statement
with open(filename1) as f1:
   with open(filename2) as f2:
      if f1.read() == f2.read():
         ...

高级方式:

import filecmp
if filecmp.cmp(filename1, filename2, shallow=False):
   ...
