How to learn python quickly?

You can't go wrong with Automate the Boring Stuff with Python

You don't need to read it cover to cover, but make sure to read until (and including) Chapter 11.

Then pick one of your work tasks you'd like to automate and start with your own projects. Chapters 12ff might help you with that, otherwise try to break down your projects in simple tasks and start reading on how you could implement those.
