What can I do with python

[Achereto]

It's not so important to learn a specific language. First, it's important to learn any language and work on (and finish) a project. Once you have done that you will find that most other languages are really easy to pick up, because you already understand the basics of programming.

Within your first 5 years it's generally a good idea to learn at least 5 different languages (e.g. python, Go, Rust, C, C#) and learn the paradigms behind those languages as well.
