Someone started on Project Euler, starting with problem #1,
so that was played with much, reinventing the wheel:

Eventually, the old stuff was discovered:

reflection is introspection in Python?

replace pyvideo.org

Dell bought EMC which owns VMware?
VMware got rid of many employees?

virtualenv is pretty much mandatory
It allows different python projects to use different versions of the same
python package, without conflicts.

pip is the preferred program for installing Python packages.

Anaconda and miniconda have conda which is also good.
