This assignment calls for us to update the array ‘test_3’ by adding 2 points to each element. Well, here’s the error message I got;

Expected “test_1_fixed” to be assigned a value

:confused:

Hi, correct me if I’m wrong, but it seems to me that the list example in this exercise is not the best way around this problem. I tried it this way and it seems to work out fine:

test_3_fixed = [x + 2 for x in test_3]

I get why arrays are very useful, but is it really necessary to overcomplicate things to make a point?

Cheers :beer:

import numpy as np

test_1 = np.array([92, 94, 88, 91, 87])

test_2 = np.array([79, 100, 86, 93, 91])

test_3 = np.array([87, 85, 72, 90, 92])

test_3_fixed=test_3+2

print(test_3_fixed)
