Depends on the kind of parsing you want to do. Python
can naturally represent binary files in string objects,
e.g.

f = open("binaryfile.bin", "rb") # notice the b for binary mode
data = f.read()
f.close()

You can then look at the individual bytes by index. People
often use the struct and array modules to simplify processing.
Whether or not you would call this "parsing", I don't know
(for me, "parsing" implies presence of a context-free or
regular grammar of some kind).
