Is there a way to encrypt files (.zip, .doc, .exe, ... any type of file) with Python?
I've looked at a bunch of crypto libraries for Python including pycrypto and ezpycrypto but as far as I see they only offer string encryption.

7In Python 2, strings are really byte-strings, so you can just read in the file as binary, encrypt it, then write as binary. – Matthew Flaschen May 30 '10 at 13:22

In Python versions prior to version 3.0, the read method of a file object will return a string, provide this string to the encryption library of your choice, the resulting string can be written to a file.
Keep in mind that on Windows-based operating systems, the default mode used when reading files may not accurately provide the contents of the file. I suggest that you be familiar with the nuances of file modes and how they behave on Windows-based OSes.

You can read the complete file into a string, encrypt it, write the encrypted string in a new file. If the file is too large, you can read in chunks.
Every time you .read from a file, you get a string (in Python < 3.0).
