I Animated an Entire Python Course from Zero | Ep 2: If, Else & Decisions
🐍 Learn Python From Zero — Episode 2: If, Else & Making Decisions (Fully Animated & Visualised)
Welcome back to Python from Zero - the fully animated Python course that teaches you programming through beautiful visualisations. In Episode 2, your code learns to think.
Until now, your programs ran top to bottom, every line, every time. Not anymore. In this episode you'll learn how to make Python choose - run one block of code when something is true, and a completely different block when it's not.
By the end, you'll build a complete Grade Calculator from scratch that takes a student's score and decides their grade — using everything you learn in this episode.

🔧 INSTALL PYTHON (BEFORE YOU START)
━━━━━━━━━━━━━━━━━━━━
This series focuses on teaching you Python concepts visually — we don't cover installation in the video so we can jump straight into the fun stuff.
It takes 2 minutes to set up:
1. Go to https://www.python.org/downloads/
2. Click the big yellow "Download Python" button
3. Run the installer (✅ tick "Add Python to PATH" on Windows!)
4. Open your terminal/command prompt and type: python --version
5. If you see a version number, you're ready to go 🎉
📖 Full install guide: https://wiki.python.org/moin/Beginner...
Mac & Linux users: Python 3 may already be installed. Type `python3 --version` in your terminal to check.
