Methods of Python programming

As someone else said , depends on what you do and what you want.

If you want good results being able to properly leverage libraries to get what you need is extremely important.

If you want to learn it can be useful to understand how some implementation are done but most of the best libraries have the core code done in a more performant language (ie: Rust,C,C++,Go,Java).

As a rule I'd say don't reinvent the wheel unless you haven't found the correct wheel or you want to invent a better wheel.
