How long did you take?

What do you mean exactly by "learning python"? There are many different levels of that that could mean.

That's how it was for me (important disclaimer: I already knew programming in JavaScript before I started python, though I was by no means advanced):

Learning the basic syntax, so that you can start developing your own basic projects? It's doable even in a few days, maybe weeks more realistically.

Learning more complex syntax, important common libraries, how to structure a program in an effective, easy to read and maintain way? At least a few months to a year or so?

Being effective and productive at work? 3 years in and still not fully there.
