我正在寻找一种方法，可以让我在比较 2 个列表时检查缺少哪些元素。很像这个线程，但我想用 NumPy Python 编写它。
import numpy as np
numbers = np.array([1,2,3,4,5,6,7,8,9])
A = np.array([2,5,6,9])
def listComplementElements(list1, list2):
storeResults = []
for i in list1:
for j in list2:
if i != j:
#write to storeResults if 2 numbers are different
storeResults.append(i)
else:
#if numebrs are equal break out of the loop
break
return storeResults
result = listComplementElements(numbers, A)
print(result) #expected result [1,3,4,7,8]
目前输出看起来像这样:[1, 1, 1, 1, 3, 3, 3, 3, 4, 4, 4, 4, 5, 6, 6, 7, 7, 7, 7 , 8, 8, 8, 8, 9, 9, 9]
我做错了什么？
