Hi,

Python interpreter consumes memory quite extensively because
"everything is object".  So constructions like:

range(1000000):

_take_ memory.  Additionally it will trigger garbage collecting code
on deallocation time so expect even more delay.
To get most out of Python - all "numbers crushing" / "pixel pushing" /
"store gigabytes" code should go to low-level compiled binary
libraries.
