A: With extreme difficulty. You may well need a different vehicle.

Think about your requirements, then implement the most appropriate data
structure. If, as is likely, you need to know which and how many files
are identical, then a set won't do the job by itself. You may need a
union-find gadget.

Then before you rush and implement something, google around and look in
the Tools and Scripts directories in the Python distribution; I'm quite
sure I've seen something like a "duplicate file detector" written in
Python somewhere.
