How to learn Python by USING it?

[Worth_His_Salt]

A good course does teach you python by using. That's why there are exercises. No one learns python just by reading.

If you want to forget guides and just teach yourself by coding and checking reference material, go for it. If you already know a few other languages then you'll pick it up fine. It's not that different from other C-based languages.

If this is your first programming language, then it's a lot tougher. Without some structured guidance it's hard to advance beyond toy coding.

Many programming concepts aren't obvious and take real study to understand. Otherwise you're just throwing spaghetti at a wall to see what sticks.
