Python Arithmetic Operators
Table of Contents
Description
Arithmetic operators are used in Python to perform basic mathematical operations on numeric values like integers, floats, and complex numbers.
Python supports the following arithmetic operators:
Operator Description Symbol
Addition Adds two values +
Subtraction Subtracts right from left -
Multiplication Multiplies two values \*
Division Divides left by right /
Floor Division Returns integer part //
Modulus Returns remainder %
Exponentiation Raises to power \*\*
Prerequisites
- Familiarity with Python syntax.
- Basic understanding of numbers and variables.
Examples
Here's a simple program in Python:
# Arithmetic Operators in action
a = 10
b = 3
# Addition
print(a + b) # Output: 13
# Subtraction
print(a - b) # Output: 7
# Multiplication
print(a \* b) # Output: 30
# Division
print(a / b) # Output: 3.333...
# Floor Division (ignores decimal part)
print(a // b) # Output: 3
# Modulus (remainder)
print(a % b) # Output: 1
# Exponentiation
print(a \*\* b) # Output: 1000 (10 to the power of 3)
