Variance can't go ahead with a intern challange

Question

Hi,
I need help with this challange.

Whit this values i have to use Python code to calculate variance the result using the corresponding equation.

I think my code is correct but sololearn no... what do you think?
Thanks!!

valores = [0, 8, 8, 9]

media = (0 + 8 + 8 + 9 )/20

total = 0

for valor in valores:
total += (valor - media)**2

c = total / media
print (c)

Answer 1

In the last step you are dividing by the mean, but you should divide by the number of elements (in this case 4)
