William’s Python Handbook

Hi, I’m William. This is my own Python reference handbook — the place I look things up while I build my creature evolution simulator in pygame.

What’s inside

• The building blocks: printing, variables, constants, f-strings
• Making choices with if / elif / else
• Lists and dictionaries — storing lots of things
• Loops — doing things over and over
• Randomness — the spark that makes evolution interesting
• Functions — little machines you build once and reuse
• Handling errors without panicking
• Classes and objects — the blueprint behind every creature
• pygame basics — a window, some shapes, and things that move
• A one-page cheat sheet for quick lookups

Built by Dad so it’s always here when I need it.
