I tried (on Linux):
lsdm: python3
Python 3.5.2 (default, Nov 23 2017, 16:37:01) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from sys import path; path.insert(0, "you-get-0.4.1128.zip/you-get-0.4.1128/src")
>>> from you_get import common
>>> common.__file__
'you-get-0.4.1128.zip/you-get-0.4.1128/src/you_get/common.py'
>>> 

This means that Python can import correctly from the (repackaged) zip archive.

Try to use "/" in place of "\" in the path specification.
The replacement may be necessary for the subpath inside the zip archive
and Python supports "/" as filepath separator even on Windows.
