如何删除NumPy数组中的数字？

Question

I want to know how I can remove the numbers resulted by the code from the original list, based on How to find larger numbers of any selected number in a series in an ascending order in NumPy?

EXAMPLE: Series of random numbers: 4, 8, 5, 9, 3, 11, 17, 19, 9, 15, 16

X=4, Then:

4, 8, 9, 11, 17, 19 (We call this ROUND 1)

The numbers resulted in ROUND 1 are removed and the operation goes for the new list as follows:

5, 3, 9, 15, 16

So if we apply the code to the new list, it will generate new results:

X=5, Then: 5, 9, 15, 16

Edit:

a = np.array([4, 8, 5, 9, 3, 11, 17, 19, 9, 15, 16])
X = 4
withreps = np.maximum.accumulate(a[np.argmax(a==X):])
result = withreps[np.where(np.diff(withreps, prepend=withreps[0]-1))]
result
# array([ 4,  8,  9, 11, 17, 19])

Answer 1

Check out the following code

import numpy as np

rand_nums = np.array([4, 8, 5, 9, 3, 11, 17, 19, 9, 15, 16])
round_one = np.array([4, 8, 9, 11, 17, 19])
res = np.setdiff1d(rand_nums, round_one)
print(res)

# output 
>>> array([ 3,  5, 15, 16])
