Python is a MUST in 2026.

This is how to be an EXPERT in 1 year: 0. Preliminary Steps

Before deciding to start, ensure you do these

⬩Know your final goal
⬩Set a target for spending daily 1 hour minimum.
⬩Research about Python ecosystem (libraries, frameworks, code editors).

P.S: This is my personal roadmap. I could spend 1 to 2 hours daily for learning and practicing during 2020. And it took me ~1 year to finish logically. It may differ from person to person.
