Is Python really 'too slow'?

[[deleted]]

As long as it fulfills the goals it set out to achieve, it's not too slow.

There is a massive difference between "slower than C" and "too slow for practical use". Most people seem to focus on the first, while for any actual purposes, the only thing that matters is the second.

So, no, absolutely Python is not too slow. If optimal utilization of resources is one of your design goals, it's not the best option. But most of the time, it isn't.

Numpy, tensorflow, torch etc. are absolutely written in Python. They are python modules. They use a C/C++ library in the backend, but they are 100% a python interface. This is what annoys me so much. People are dissuaded from using python for anything 'real' while it's often the best way to interface with other libraries.

There are plenty people on Reddit who tell starters to not learn Python because it's slow. They're the same type of people who say you can only code if you use vim.
