def run():
    func_dict = {
        '1': {'title': "第一部分", 'func': "page.execute"},
        '2': {'title': "第二部份", 'func': "search.execute"},
        '3': {'title': "第三部分", 'func': "download.execute"},
    }
    tips = ";".join(["{}.{}".format(k, v['title']) for k, v in func_dict.items()])
    while True:
        print(tips)
        choice = input("请输入序号(Q/q退出)：")
        if choice.upper() == 'Q':
            break
        data_dict = func_dict.get(choice)
        print(data_dict)
        if not data_dict:
            print(data_dict)
            print("序号不存在，请重新输入！")
            continue
        print(data_dict['func'])#()
