It is all relative. If you want to write fast moving graphics etc then
yes, you probably need C++. For anything else you might find Python is
fast enough.
A good approach tends to be: write it in Python first, benchmark it, find
out *if* it's too slow. If so, find out *what* exactly is too slow,
optimise that code, benchmark again. Iterate. If there are still parts that
are too slow, move the 1-5% of your code that are most time critical into
Cython. Benchmark, optimise. Iterate. And only *then*, move on to plain
C/C++ if you can really prove with verified benchmarking numbers that you
need to. In almost all cases, you don't. In any case, it will safe you all
of the hassle of writing the entire code in C/C++, which usually safes you
weeks, months or years of developer time, depending on the complexity of
your application.
