Working with Numbers in Python
Numbers play a crucial role in programming, and Python provides robust support for working with them. In this topic, we'll explore everything you need to know about working with numbers in Python, from basic arithmetic operations to more advanced mathematical functions and concepts.
Basic Arithmetic Operations
Addition
Addition is the process of combining two or more numbers to find their sum.
# Example of addition
result = 5 + 3
print(result) # Output: 8
Subtraction
Subtraction is the process of finding the difference between two numbers.
# Example of subtraction
result = 10 - 3
print(result) # Output: 7
Multiplication
Multiplication is the process of repeated addition and finding the product of two numbers.
# Example of multiplication
result = 4 * 5
print(result) # Output: 20
Division
Division is the process of splitting a number into equal parts or finding the quotient of two numbers.
# Example of division
result = 10 / 2
print(result) # Output: 5.0
Floor Division
Floor division returns the quotient of the division, discarding any remainder.
# Example of floor division
result = 10 // 3
print(result) # Output: 3
Modulo
Modulo returns the remainder of the division operation.
# Example of modulo
result = 10 % 3
print(result) # Output: 1
Advanced Mathematical Functions
Exponentiation
Exponentiation raises a number to the power of another number.
# Example of exponentiation
result = 2 ** 3
print(result) # Output: 8
Square Root
Square root returns the square root of a number.
# Example of square root
import math
result = math.sqrt(16)
print(result) # Output: 4.0
Trigonometric Functions
Python’s math module provides various trigonometric functions such as sine, cosine, and tangent.
# Example of trigonometric functions
import math
angle = math.radians(90) # Convert angle to radians
sin_result = math.sin(angle)
cos_result = math.cos(angle)
tan_result = math.tan(angle)
print(sin_result, cos_result, tan_result) # Output: 1.0 6.123233995736766e-17 1.633123935319537e+16
