Test if a numpy array is a member of a list of numpy arrays, and remove it from the list

Question

When testing if a numpy array c is member of a list of numpy arrays CNTS:

import numpy as np

c = np.array([[[ 75, 763]],
                  


        

Answer 1

Use del to delete the index of the list you want to remove.

del CNTS[int(np.where(list(np.array_equal(row, c) for row in CNTS))[0])]

CNTS

[array([[[  78, 1202]],

        [[  63, 1202]],

        [[  63, 1187]],

        [[  78, 1187]]]), array([[[ 72, 742]],

        [[ 58, 742]],

        [[ 57, 741]],

        [[ 57, 727]],

        [[ 58, 726]],

        [[ 72, 726]]]), array([[[ 66, 194]],

        [[ 51, 194]],

        [[ 51, 179]],

        [[ 66, 179]]])]
