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 :

Square root of a number -
Square root of a number –
Square root of a number -
Square root of a number –
