Automate the boring stuff and Python Crash Course are 2 standard books that are often recommended. The first one is freely available as PDF. I haven't read them myself though.

I learned Python by starting with a project and then seeking out tutorials for helping with that subject.

My project was a simple website, so the Django Project's official tutorial was where I spent most of my time. These days it's still excellent, and there's now Django Girls who host a larger set of tutorials as well.

Maybe you're not interested in web stuff, and that's fine. My advice would be to figure out what you want to learn more specifically and look for tutorials for that. If nothing else, it'll make the learning process more interesting.

I have a list of curated resources here: https://learnbyexample.github.io/py_resources/

There are sections for beginners, intermediate, advanced, etc. Also included are exercises, projects, debugging, testing, and many more stuff. Hope it helps :)
