将两个列表的不同数据合并为一个

list1 = [1, 2, 3, 4, 5]
list2 = [4, 5, 6, 7, 8]

set1 = set(list1)
set2 = set(list2)

merged_set = set1.union(set2)
merged_list = list(merged_set)

print(merged_list)

list1 = [1, 2, 3, 4, 5]
list2 = [4, 5, 6, 7, 8]

merged_list = [x for x in list1 + list2 if x not in list1 or x not in list2]

print(merged_list)

list1 = [1, 2, 3, 4, 5]
list2 = [4, 5, 6, 7, 8]

for item in list2:
    if item not in list1:
        list1.append(item)

merged_list = list1

print(merged_list)
