如何从Python列表中删除重复项并保持顺序？

my_list = [1, 2, 2, 3, 4, 4, 5]
unique_list = []
[unique_list.append(i) for i in my_list if i not in unique_list]
print(unique_list)

my_list = [1, 2, 2, 3, 4, 4, 5]
unique_list = list(dict.fromkeys(my_list))
print(unique_list)

from collections import OrderedDict
my_list = [1, 2, 2, 3, 4, 4, 5]
unique_list = list(OrderedDict.fromkeys(my_list).keys())
print(unique_list)
