Python operators enable you to perform computations by combining objects and operators into expressions. Understanding Python operators is essential for manipulating data effectively.
This tutorial covers arithmetic, comparison, Boolean, identity, membership, bitwise, concatenation, and repetition operators, along with augmented assignment operators. You’ll also learn how to build expressions using these operators and explore operator precedence to understand the order of operations in complex expressions.
By the end of this tutorial, you’ll understand that:
- Arithmetic operators perform mathematical calculations on numeric values.
- Comparison operators evaluate relationships between values, returning Boolean results.
- Boolean operators create compound logical expressions.
- Identity operators determine if two operands refer to the same object.
- Membership operators check for the presence of a value in a container.
- Bitwise operators manipulate data at the binary level.
- Concatenation and repetition operators manipulate sequence data types.
- Augmented assignment operators simplify expressions involving the same variable.
This tutorial provides a comprehensive guide to Python operators, empowering you to create efficient and effective expressions in your code. To get the most out of this tutorial, you should have a basic understanding of Python programming concepts, such as variables, assignments, and built-in data types.

Getting Started With Operators and Expressions
In programming, an operator is usually a symbol or combination of symbols that allows you to perform a specific operation. This operation can act on one or more operands. If the operation involves a single operand, then the operator is unary. If the operator involves two operands, then the operator is binary.
For example, in Python, you can use the minus sign (-) as a unary operator to declare a negative number. You can also use it to subtract two numbers:
