zlib is part of the standard library. It should have been there when you

Don't do that.
?* that's not a Python package. It has no business being in the Python
?* don't put things into the Python path willy-nilly. Let the canonical
tools (i.e.: pip, setup.py files, etc.) take care of it.
?* DEFINITELY don't put your own stuff into the *standard* library
location. Use site-packages/ for custom packages.
Install Python again from scratch. If you can't import zlib and zipfile
in a *clean* Python install, come back and tell us how you installed
Python and what OS/distribution you're using. Then I'm sure we can help
you figure out what went wrong.
If you installed from source and you didn't have zlib headers installed
at the time, I could imagine this happening... but I have no idea if
Python would even build without zlib.
