Python Foundations: Values and Expressions

Learners meet Python's four basic types (int, float, str and bool), evaluate arithmetic expressions with the order of operations, floor division and remainder, and join and repeat strings. They practise predicting the exact output of print statements, the skill that every later trace depends on.
