How can I compare if 2 files has duplicate entries in python?

[yinglcs]

I am new to python. How can I compare if 2 files has duplicate entries
in python?
Is there an example for that? What if the files are big and I don't
want to read the whole file in memory.

Thank you.

You need to supply more info. If you just want to determine if two
files are exactly alike you can just calculate the md5 checksum or
each file. If they are different, the files are different. See:

http://docs.python.org/lib/module-md5.html


If you want to compare files line by line see following:
