Python Intermediate Tutorial - Decision Structures, Loops, Functions, and Modules

Learn intermediate Python programming concepts through hands-on practice with decision structures, loops, functions, and modules. Master if, elif, and else statements along with boolean logic and comparison operators to create programs that make intelligent decisions. Explore while loops for condition-based repetition and for loops for iterating through data structures like strings and ranges, while learning to avoid common pitfalls like infinite loops and implement proper input validation. Build your own custom functions that accept parameters and return values, organize code using main() functions, and import built-in modules like math to leverage existing functionality. Apply these concepts through practical programming challenges including creating a password checker and an interactive pizza order calculator that demonstrates real-world problem-solving techniques. Develop skills in debugging code, improving program output, and structuring larger programs using hierarchy charts and modular design principles that make code more maintainable and reusable.
