In this short guide, I’ll show you different ways to square a number in python. So let’s start by discussing its math definition.
In mathematics, the square of any integer number is the product of that number with itself.
For instance, 3×3 = 9 .Which implies square of 3 is 9.
1. By Using Exponential Operator
The builtin exponential operator represented by ** takes two real numbers as an argument and performs the arithmetic exponential operation on them. For example 8**3 = 8^3 = 8x8x8 = 512
In the following code, we have used an exponential operator to square a number in python.
# program to square a number in python number = 25 square = number**2 # calculate the square print(square)
Here is the output of above code.
2. By Multiplying Number Two Times
In this code example, we multiplied the input number with itself to obtain its square.
number = 25 square = number*number # calculate the square print(square)
3. By Using math.pow() Function
math.pow(x,y) function from the builtin maths library takes x and y as an argument and returns x to the power y.
# how to find the square of a number in python import math number = 25 square = math.pow(number) # calculate the square print(square)
