Python—合并两个有序列表

def hb(list1,list2):
    result = []
    while list1 and list2:
        if list1[] < list2[]:
            result.append(list1[])
            del list1[]
        else:
            result.append(list2[])
            del list2[]
    if list1:
        result.extend(list1)
    if list2:
        result.extend(list2)
    print(result)
    return result

list1 = [,,,,]
list2 = [,,,,,]
hb(list1, list2)
