square root function on Python using Spyder

Question

I'm just starting out using both Python under Spyder. I was about to do a simple square root calculation. I see that in Python, you need to do an "import math". I did that in Spyder and got an error: 'math' imported but unused. I tried using sqrt() but that threw an error. There's something fundamental I'm missing here. I did a bunch of searching and still have not been able to figure this issue out. Any help would be greatly appreciated.

thanks! clem

Answer 1

I can think of 3 options.

1:

import math

n = 5

print(math.sqrt(n))

2:

from math import sqrt

n = 5

print(sqrt(n))

3:

n = 5

print(n ** 0.5)
