How can i define a function in python to calculate the square root of a number?

Answer 1

from math import sqrt
print (sqrt (100))

Answer 2

def sq_rt(x):
return x**.5

Answer 3

I would just add that there is no point in reinventing the wheel - just use math.sqrt() :)

Answer 4

First thing first, you must import module math.

So, the code may be like this :

import math
def calculate_square_root(x):
value=math.sqrt(x)
print (value)

calculate_square_root(36) #number in parentheses can be changed as you like
