What do you mean by subtraction? Can you tell what is the expected output?

while b: x = b.pop() if x in a: a.remove(x) # now `a` is your desired output Edit: do you need a code snippet or is this sufficient?

a = [3,4,5,6] b = [3, 4] print([i for i in a if i not in b]) #5 6 import numpy as np a = np.array([3,4,5,6]) b = np.array([1,2,3,4]) print(a - b) #2 2 2 2
