How much fast or slow is python compared to other popular programming languages like c, cpp, java, c#, JavaScript e.t.c?

Answer 1

I believe the speed difference may not be an issue, depending on the application.

Answer 2

Python is slower than JavaScript, C#, C and C++. Maybe 10 times slower than C (I think). But, some libraries like numpy are written in C, so you can use it instead of Python List to get better performance.
