Lots of production software is written in Python, for better or for worse. In fact, production software gets written in every language eventually, no matter the intent of its designers. Maybe you only write your production software in C and C++, in which case good for you.
I do write Python code used in production, but does that doesn't make it serious production software.
It takes a lot of effort to make a Python program not break on some inputs, so it's not really fire and forget like it is with C++. It's possible but it requires many more iterations.

Seriously questionable assertion to my eyes. Maybe I just haven't used C++ in way too long to appreciate that it's true. I have heard lots of people say that modern C++ is really great.
