How to Learn Python as a High Schooler (90-Day Plan)
Python is the best first programming language for high schoolers. Readable, widely used, great for AP Computer Science.
Quick answer
Days 1-30: syntax. Days 31-60: data structures + first projects. Days 61-90: build a real thing. 30-45 min/day, 5 days/week.
Days 1-30: Fundamentals
- Variables, data types, print/input
- If/elif/else
- For and while loops
- Functions: define, call, parameters, return
Days 31-60: Data + first projects
- Lists and dictionaries
- Files and modules (random, math, datetime)
- Error handling (try/except)
- First small project: calculator, number guesser, quiz app
Days 61-90: Build something real
- Text game (Hangman, Tic-Tac-Toe)
- Data analysis: read CSV, compute stats
- Web scraper (requests + BeautifulSoup)
- Discord bot
- Math tool (quadratic solver)
Most important: finish the project. A small finished project teaches more than half-built ambitious ones.
Best resources
- Python.org Tutorial — free, official
- Real Python — quality articles
- freeCodeCamp YouTube — long-form courses
- Replit — code in browser, no setup
What to avoid
- Jumping to ML before basics
- Watching tutorials without coding along
- Switching languages every few weeks
- Tutorial hell — eventually build without a tutorial
