Task :

To find square root of a given number.

Approach :

• Read input number for which the square root is to be calculated using input()orraw_input().
• Pass that number to sqrt method from Math module sqrt(num).
• sqrt method will return the square root of the number passed.
• Print the result.

Program :

import math
num = float(input('Enter a number: '))

print('The square root of %0.3f is %0.3f' % (num, math.sqrt(num)))

Output :
