Instead of the typical foo/bar examples, I used scenarios that beginners actually encounter: - Shopping cart systems for list operations - Login authentication for while loops - Grade calculators for enumerate/zip - Expense trackers combining multiple concepts
Each example is complete, runnable code with real output shown.
Key decisions I made: 1. Every code snippet solves an actual problem (not just demonstrating syntax) 2. Showed both "old way" and "modern way" for concepts like list comprehensions 3. Included a complete project at the end (expense tracker with categorization) 4. Common mistakes section based on bugs I actually encountered
The guide covers lists, tuples, for/while loops, range, enumerate, zip, comprehensions, filter/map, and lambda functions.
Target audience: people who've finished basic Python syntax tutorials and are asking "okay, but how do I build something with this?"
Open to feedback on: - Which examples felt most/least practical - What fundamental concepts I should have covered but didn't - Better ways to explain mutability vs immutability
Happy to answer questions!
