    I got 2.94 if I run the code in VScode, but I got Runtime error when I submitted it. What was the error?

    import numpy as np

A = [1, 2, 3]
stdA = np.std(A)

mn = float('inf')
N = 0
for i in np.arange(0, 4.01, 0.01):
    B = [1, 2, 3, i]
    stdB = np.std(B)
    if (abs(stdA - stdB) <= mn):
        mn = abs(stdA - stdB)
        N = i

print(N)
