Striving for PEP-8 compliance

Hi all

I've written a bunch of internal libraries for my company, and they
all use two space indents, and I'd like to be more consistent and
conform to PEP-8 as much as I can.

My problem is I would like to be certain that any changes do not alter
the logic of the libraries. When doing this in C, I would simply
compile each module to an object file, calculate the MD5 of the object
file, then make the whitespace changes, recompile the object file and
compare the checksums. If the checksums match, then the files are
equivalent.

Is there any way to do something semantically the same as this with python?

Cheers

Tom
