Python Basics

Explore Python's seven math operators—addition, subtraction, multiplication, division, exponentiation, integer division, and modulo—through clear examples like 10 + 2 = 12 and 10 // 3 = 3.

Use Python as a calculator by performing addition, subtraction, multiplication, division, exponentiation, floor division, and remainder with integers and decimals, and understand right-to-left exponentiation and parentheses in expressions.

Master using the IDLE editor and shell to write and save Python code as .py files, then run it and print results with the built-in print function.

Learn how variables act as containers storing values and how the assignment operator links a name to a value. Understand case sensitivity, initialization, and descriptive names for readability.

Learn how to write readable Python code using comments to explain logic, using hash-based single-line and triple-quoted multi-line comments, and to temporarily disable code for debugging.

Explore Python data types—integers, floats, strings, and booleans—and learn to determine and convert them using type, int, float, string, and bool functions. See how variables can change type at runtime.

Explore how the input function collects user data as strings and converts it to numbers with int() or float() for arithmetic, prompts in input(), and printing results.

Learn to use the print function in Python to display items, combine strings and variables, and manage spaces with comma or plus, while collecting name and age with input.

Learn the six Python comparison operators: ==, !=, <, >, <=, and >=. See how each evaluates examples like 2 == 2, 2 != 5, and 5 < 6.
