# Python program to find the square root

In this program,you  will about the python program how to find the square root of any number

by two method:

By using exponent function

By using the cmath module.

For understand the program you have the knowledge:

• Python input,output.

• Python data types.

• Python operators.

# Example for square root of positive number

Code:

# Python Program to calculate the square root for positive number

number = 10

number_sqrt = number ** 0.5

print('square root %0.3f is %0.3f'%(number ,number_sqrt))

Output:

square root 10.000 is 3.162

In the above program,value is store in the number variable and then exponent with help ** operator

with power 0.5(½) store in the number_sqrt variable.At the end of the program,display with

help of print function.

## Example for For real and complex number:

Source code:

`

import cmath

number = 2+2j

number_sqrt = cmath.sqrt(number)

print('square root  {0} = {1:0.3f}+{2:0.3f}j'

.format(number ,number_sqrt.real,number_sqrt.imag))

In the above example,import the library cmath and store the  complex number

in the number variable .Use the cmath.sqrt( ) function to find the square root.

Display with help of print function.
