如何在循环中删除列表中的元素？

my_list = [1, 2, 3, 4, 5]
for i in range(len(my_list)-1, -1, -1):
    if my_list[i] == 3:
        del my_list[i]
print(my_list)

my_list = [1, 2, 3, 4, 5]
i = 0
while i < len(my_list):
    if my_list[i] == 3:
        del my_list[i]
    else:
        i += 1
print(my_list)

my_list = [1, 2, 3, 4, 5]
my_list = [x for x in my_list if x != 3]
print(my_list)
