有效地将n个列表一起扩展

def extend_lists(*lists):
    result = []
    for lst in lists:
        result.extend(lst)
    return result

# 示例用法
list1 = [1, 2, 3]
list2 = [4, 5, 6]
list3 = [7, 8, 9]
extended_list = extend_lists(list1, list2, list3)
print(extended_list)

list1 = [1, 2, 3]
list2 = [4, 5, 6]
list3 = [7, 8, 9]
extended_list = list1 + list2 + list3
print(extended_list)

from functools import reduce

list1 = [1, 2, 3]
list2 = [4, 5, 6]
list3 = [7, 8, 9]
extended_list = reduce(lambda x, y: x + y, [list1, list2, list3])
print(extended_list)

const list1 = [1, 2, 3];
const list2 = [4, 5, 6];
const list3 = [7, 8, 9];
const extendedList = [...list1, ...list2, ...list3];
console.log(extendedList);
