[FIXED] How to cut the lower values when caclulating percentile?

Issue

If I calculate 90 percentile using numpy:

import numpy as np

a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
p = np.percentile(a, 90)
print (p)

It cuts the highest value so the result is:

9.1

How to cut instead the lower values so the output would be:

2

Thank you!

Solution

You want the 10th percentile, not the 90th.

p = np.percentile(a, 10)
print (p)
# 1.9
