Python Programming · Foundations

Write your first programs. Print messages, keep values in variables, and let Python do the arithmetic. Every lesson runs in your browser.

Ask questions with input(), work with words and text, and set up Python on your own computer.

Teach your program to choose. Use if, elif and else, and join conditions with and, or and not.

Repeat work with for loops over a range or a list, and with while loops that run until something changes.

Keep many values in one list, wrap your code in functions, and put it all together in small projects.
