# Python Program to Find the Square Root of Number

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```

## Python Program to Find the Square Root of Number

Follow the following algorithm to write a python program to find the square root of number:

• Find square root of a number in python without using sqrt
• Python program to find square of a number using sqrt() function

### 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```

### Python program to find square of a number using sqrt() function

Follow the below steps and write program to find square of a number using sqrt() function in python:

• Import math module in program
• Allow the User to input any number
• Calculate square root of number using sqrt() function
• Print square root
```# Python program to find square root of the number

import math  # math module

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

# display result
print('Square root = ',math.sqrt(num))```

After executing the python program, the output will be:

```Enter the number: 16
Square root = 4.0```
