[FIXED] How do I calculate square root in Python?

Issue

Why does Python give the "wrong" answer?

x = 16

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

Yes, I know import math and use sqrt. But I'm looking for an answer to the above.

Solution

sqrt=x**(1/2) is doing integer division. 1/2 == 0.

So you're computing x^(1/2) in the first instance, x⁽⁰⁾ in the second.

So it's not wrong, it's the right answer to a different question.
