python sqrt: 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

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

Answer 1

Python is giving you the wrong answer because  sqrt=x**(1/2) is doing integer division. 1/2 == 0.

This is the correct answer because 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.
