is there any kind of performance gain while using .pyc files in python?

Question

We can write a piece of python code and put it in already compiled ".pyc" file and use it. I am wondering that is there any kind of gain in terms of performance or it is just a kind of modular way of grouping the code.

Thanks a lot

Answer 1

There is no performance gain over the course of your program. It only improves the startup time.

A program doesn't run any faster when it is read from a ‘.pyc’ or ‘.pyo’ file than when it is read from a ‘.py’ file; the only thing that's faster about ‘.pyc’ or ‘.pyo’ files is the speed with which they are loaded.

And pyo files being the next optimization just remove doc strings from your code.
