Run a ready to go Python project

[snippsat]

My question is, how can I run this Python project ? Don't get me wrong, but what should I searching for in order to run the main project ?

I depend on the project,it's usually some documentation.

python setup.py --install

This is the old way we used before,now is pip most used and are distributed at PyPi,often in cooperation with a GitHub,BitBucket..ect Repo.
If shall use this method it usually documented in in Repo.
If post link to Repo,then can we look at it.
