Best Site for Learning Python
Summary
The best site for learning Python is CS50P from Harvard — free, university-grade, with the same instructional rigor as the famous CS50 course. freeCodeCamp's Python certifications are the best fully-free runner-up. Boot.dev is the right pick if you want gamified back-end-focused learning. Real Python's tutorials remain the gold standard for intermediate-to-advanced topics. Codecademy works for absolute beginners but its paid tier has gotten expensive relative to what you get.

Frequently asked questions
Can I really learn Python free?
Yes. CS50P and freeCodeCamp combined cover everything from fundamentals through job-ready skills, both fully free at the audit and certification tiers. Real Python's free articles fill specific gaps. Paid tools accelerate but are not required.
How long does it take to learn Python?
Basic literacy in two to three months of consistent daily practice. Employable for entry-level data or scripting roles in six to twelve months including portfolio work. Specialization in machine learning or backend takes longer.
Which Python version should I learn?
Python 3.12 or later. Python 2 was end-of-life in 2020 and any tutorial still teaching it is too old. New courses should be targeting recent 3.x versions, with awareness of features added in 3.10 and beyond.
Do I need a CS degree to get a Python job?
No. Many Python developers come from non-CS backgrounds. A portfolio of substantive projects, demonstrated knowledge of fundamentals, and ability to discuss your code are what hiring managers evaluate. CS degrees help in some employers and roles but are not required.
What's the next language to learn after Python?
Depends on direction. JavaScript for full-stack web. SQL for data work. Go or Rust for backend systems. C for understanding what's under the hood. Most working developers know multiple languages — Python is rarely the only one.
