我无法在 Visual Studio Code 上使用“from math import sqrt”

Question

I'm new to this site, I'm recently trying to learn how to code in Python again, and now I'm doing an exercise that I could complete, but it's happening something that is annoying me. I can import math successfully, but somehow, VSCode just doesn't want to recognize "from math import sqrt". Here's my code so anyone can help me. Thank you.

import math  # (from math import sqrt would be here, but doesn't work so I put import math)

a = int(input('Digite o primeiro número: '))
b = int(input('Digite o segundo número: '))

c = a**2+b**2
resultado = math.sqrt(c)

print(f'O comprimento da hipotenusa é de {resultado}')

Answer 1

If you do from math import sqrt then you have imported only sqrt and not math. So in this case resultado = math.sqrt(c) should be resultado = sqrt(c) instead.

Mathias answered it in the comments; thank you.

Answer 2

you dont need the math module, you can instead do:

c = (a**2+b**2)**0.5

as square rooting a number is equal to power it to 1/2.
