This document covers Python expressions and variables, including arithmetic operations, assignment, variable naming conventions, and practical examples for storing and manipulating values efficiently.

Introduction

Expressions in Python describe operations performed by the computer, such as arithmetic calculations. Variables are used to store and reuse values in code.

Python Expressions

Expressions are combinations of operands and operators that produce a result.

Arithmetic Operations

Addition (+): Adds numbers. Example: 100 + 60 results in 160.
Subtraction (-): Subtracts numbers. Example: 10 - 20 results in -10.
Multiplication (*): Multiplies numbers. Example: 5 * 5 results in 25.
Division (/): Divides numbers. Example: 25 / 5 results in 5.0; 25 / 6 results in approximately 4.167.
Integer Division (//): Divides and rounds down to the nearest integer. Example: 25 // 6 results in 4.

Python follows mathematical conventions, performing multiplication before addition unless parentheses change the order.
