Python Intermediate

You’ll learn how to control program flow using if, elif, and else decision structures, how booleans and logical operators like and, or, and not work, and how Python evaluates conditions step by step. You’ll practice loops — both while loops that run until a condition changes and for loops that iterate through strings, ranges, and other data — including how to avoid infinite loops and validate user input. You’ll also start writing your own functions, passing and returning values, using a main() function to organize your program, and even importing built-in modules like math to reuse code instead of rewriting it. By the end, you’ll have built and tested small interactive programs (like a password checker and a pizza order calculator) and learned how to plan larger programs using structure and hierarchy.
