6. How to Choose the Right Python Course
Learning Style
If you prefer video lectures with a visible instructor, go for Udemy courses or Coursera/EdX. If you prefer reading and working at your own pace, Real Python or Automate the Boring Stuff are ideal. If you want interactive coding without any setup, Codecademy or DataCamp are your best bets.
Time Commitment
If you can dedicate full-time hours, CS50's Python track or a bootcamp-style Udemy course will get you to a working level in 4–8 weeks. If you're learning part-time (5–10 hours/week), Python for Everybody or Automate the Boring Stuff is more realistic — expect 3–6 months to reach intermediate proficiency.
Your Goal Drives the Curriculum
Don't take a "general Python" course if you know you want to do data science. The best data science course teaches Python basics in weeks 1–2 and then dives into pandas and NumPy. A general Python course will spend weeks on topics (like object-oriented programming) that are less relevant to data work.
7. Frequently Asked Questions
How long does it take to learn Python?
For basic proficiency (writing scripts, understanding code, building simple programs): 2–3 months of part-time study. For job-ready proficiency in a specific domain (data science, web dev): 6–12 months of consistent study and project building. The key word is "consistent" — 1 hour every day beats 8 hours once a week.
Should I learn Python 2 or Python 3?
Python 3 only. Python 2 reached end-of-life in January 2020 and is no longer supported. Every current library, framework, and job posting uses Python 3. Any course teaching Python 2 is outdated and should be avoided.
Do I need a computer science degree to get a Python job?
No. Many Python developer roles — especially in data science, web development, and DevOps — hire self-taught programmers. What matters is: (1) demonstrated Python skills via a portfolio, (2) relevant projects, and (3) passing technical interviews. Online course certificates are nice-to-have but not required.
What's the best Python IDE for beginners?
Start with VS Code (free, Microsoft) with the Python extension — it's lightweight, powerful, and used by professionals. As you grow, PyCharm Community Edition (free) offers more advanced features for larger projects. Avoid IDEs with heavy setup; you want to spend time coding, not configuring.
Is Python or JavaScript better for beginners?
Both are excellent first languages. Python is generally considered slightly easier due to its more English-like syntax. JavaScript has the advantage of being immediately visible (you can build web pages), while Python requires a terminal to see output. If your goal is web development, start with JavaScript. For data science, AI, or general programming — start with Python.
Our Top Recommendation
For complete beginners who want the best free education: start with freeCodeCamp's Python for Everybody on YouTube or CS50's Python — both are world-class and cost nothing.
For those serious about data science or ML careers: combine the free basics course with Jose Portilla's Data Science Bootcamp on Udemy (frequently on sale for under $20). For web development: pair Python basics with the official Django tutorial and FastAPI documentation.
The best course is the one you'll actually finish — factor in your learning style, schedule, and specific goals before choosing.
