Python can run code inside a zip archive. This explains why some code starts with a friend #!/usr/bin/env python, immediately followed by bytes of the raw zip file. See http://sayspy.blogspot.com/2010/03/various-ways-of-distributing-python.html
Python also allows users to run the python debugger conveniently for almost any code from the command line using the -m pdb option. But running this program with a zipper (for example, the popular youtube-dl program ) leads to an encoding error as follows:
$ python -m pdb /usr/bin/youtube-dl -h
Traceback (most recent call last):

the PEP 263 link does not talk about zip, and I'm not sure where this zip function is officially described or implemented.
