how to download a tarball on github?

[Skaperen]

i don't want to see tarballs contained in a package, i want a tarball (instead of a zip file) of the package, possible for every package (on github).  is that what that will do?

You seems to be confusing about terms here.
You get the whole Repo as tarball,as i show with curl command in my post.
It's just the same content as Dowload ZIP,just that's is a a tarball. 
Or uncompressed with git clone repo.

A Package is more language specify,and has nothing to do what's shared on Github.
Sure a Python Repo usually have a setup.py so there is possible to make a package,
but most of the time this is already done bye owner of Repo and then package is shared on PyPi.
So Textblob Repo as i used as demo also have a PyPi link.
There also link to wheel files(which get made under package creation with setup.py).
