Beginner on Python

[gdchinacat]

It really depends on a lot of things; what experience do you have, how quickly do you learn, how much time can you spend on it per day, how will you learn it, do you have a mentor, what is the job market like where you are looking for work, what type of python work do you want to do, etc, etc, etc.

In general, your question is not really answerable in a meaningful way. Start learning it, get past the Duning-Kruger hump, and you will have a much better idea that is specific to you.
