To add to the answers of Andrew Hare and Baishampayan Ghose...
To learn the idiom of any language must involve reading code written in that idiom. I'm still learning the Python idiom, but I've been through this with other languages. I can read about list comprehensions, but the lightbulb only really comes on when you see such things in use and say, "Wow! That's awesome! Two lines of code and it's crystal clear!" So go find some pythonic code that you find interesting and start reading it and understanding it. The knowledge will stay in your head better if you see everything in the context of a working program.
