list 删除指定位置元素

list = [1, 10, 3, 20, 60, 100, 6]
想删除第 3，7 个元素，假如只知道下标为 del_index = [2, 6]

下面这样是不对的，因为pop之后会改变index！！

for i in del_index:
    list.pop(i)

print(list)

应该：先把元素存起来，再 remove！

del_elems=[]
for i in del_index:
    del_elems.append(list[i])

for elem in del_elems:
    list.remove(elem)

print(list)
