how do i calculate square root in python

Question

Why does Python give the "wrong" answer?

x = 16

sqrt = x**(.5)  #returns 4
sqrt = x**(1/2) #returns 1

Answer 1

you can start by primarily import math module of python  and using the sqrt function .

But for the above code sqrt=x**(½) simply perform what we called integer division 

First it calculate x(½) and then x(0) ==1

So the answer of this kind equation will always be 0,no matter whatever be the value of x.

So the recommended way is to go with sqrt=X**(.5)
