Python is neither Java nore C++ and there are significant differences.
It requires different language specific habits.

Today's desktops literally match the supercomputers of enough years
ago and make many slow-computer habits (like writing lots of
assembler) generally obsolete.  The fast computer paradigm: write
something relatively simple that works.  If not fast enough (and it
often will be fast enough), then profile and optimize hotspots.
