Python Syntax & Setup

Python is one of the world's most widely used languages for automation, data work, and backend systems — precisely because it reads almost like plain English. Instead of curly braces, Python uses indentation (consistent spacing) to group statements, which forces clean, readable code from day one.

• Variables need no type declaration: name = "Grace" just works.
• Core data types: str, int, float, bool.
• print() and input() handle output and keyboard input.
• A script runs top to bottom with python filename.py — no compile step.

💡 Practical Skill: Install Python and VS Code (with the Python extension), then run your first script from the integrated terminal. Track your work with Git from lesson one — professional habits start early.
