This module is mostly the same like the builtin module zipimport. While zipimport imports from a zip file, and memzipimport imports from zipped content in memory.

import sys
sys.memzip = {"library.zip": bytearray(open("lib.zip", "rb").read())}
sys.path.insert(0, "library.zip")
sys.path_hooks.insert(0, memzipimport.zipimporter)

There are three steps:

• store zipped content in sys.memzip as an bytearray
• insert a virtual library path
• insert path hooks
