import numpy as np

heights = [189, 170, 189, 163, 183, 171, 185, 168, 173, 183, 173, 173, 175, 178, 183, 193, 178, 173, 174, 183, 183, 180, 168, 180, 170, 178, 182, 180, 183, 178, 182, 188, 175, 179, 183, 193, 182, 183, 177, 185, 188, 188, 182, 185, 191]

heights_arr = np.array(heights)
print((heights_arr > 188).sum())

Answer 3

Sorry i did not write the code

Answer 4

It is finding each element that is greater than 188, and it is keeping a running tally of each. Basically it is adding or counting each entry above 188. That is what sum is doing here
