In this tutorial you will learn about the Python Program to Find the Square Root and its application with practical example.
In this tutorial, we will learn to create a Python Program to Find the Square Root using Python Programming.
Prerequisites
Before starting with this tutorial we assume that you are best aware of the following Python programming topics:
- Python Operator.
- Basic Input and Output
- Basic Python programming.
- Python if-else statements.
- Python Loop.
What is Square root?
So the Squares root of a number is found when number is multiplying the number itself twice 6 * 6= 36. Where a square root of a number on getting multiplied by itself gives the original √36 = 6. A square root of a number ‘a’ is a number b such that b² =a.
Python Program to Find the Square Root
In our program, we will create a Python Program that Find the Square Root of a given number.First we would declared and initialized the required variables. Here in this program we are going find Square root of a given number first of all we take a value from user and pass this value to in-built function to find Square root of a number.

# Python Program to calculate the square root # To take the input from the user number = float(input("enter any number to find its square root")) # Calculating square root sqrt = number ** 0.5 # printing square root of given number print('The square root of %0.0f is %0.0f'%(number ,sqrt)) |
Output
in our program, we have first declared and initialized a set variables required in the program.
- number= it will hold value given by user.
- sqrt= it will hold square root of a number
First of all in our program we will take all required variable and value, and then take value from user at run time and the value given by user will be convert to int from string (as in python the value we take from input from user are always string so we need to convert it into int) and will be stored into variable called ‘number’.
After taking these values from user we will calculate the square root a given number.
Find the square root by applying the “**” exponent operator.our program only works for Positive real numbers.And at last after calculating Square root finally we will print the value of variable ‘sqrt’ to get our desired result.i.e square root of a number.
