Python program to find square root of number; In this tutorial, you will learn how to find the square root of number in python programming.

The square root of a number is a number that, when multiplied by itself, equals the desired value. So, for example, the square root of 49 is 7 (7×7=49). The process of multiplying a number times itself is called squaring.

Using the following formula, you can write a python program to find the square root of number:

x2 = y 

x = ±√y

Find square root of a number in python without using sqrt

Follow the below steps and write a program to find square root of number in Python:

Allow the User to input the number.
Calculate square root with this formula sqrt = num ** 0.5.
Print the square root of number.

# Python program to find square root of the number

# take inputs
num = float(input('Enter the number: '))

# calculate square root
sqrt = num ** 0.5

# display result
print('Square root of %0.2f is %0.2f '%(num, sqrt))

After executing the python program, the output will be:

PEnter the number: 4
Square root of 4.00 is 2.00
