python创建列表并查询
python列表使用实现名字管理系统本文实例为大家分享了python列表使用实现名字管理系统的具体代码，供大家参考，具体内容如下
实现的功能代码如下：
|
|
# 名字管理系统 列表的使用print("="*50)print("1:添加名字")print("2:修改名字")print("3:查询名字")print("4:删除名字")print("5:退出")print("="*50)names = [] while True: num = int(input("请输入要操作的序号：")) # input获取到的是str，要转换为Int if num == 1: name_add = input("请输入要添加的名字：") names.append(name_add) print(names) elif num == 2: name_edit1 = input("请输入要修改的原始名字") # 法一： # if name_edit1 in names: # for i in range(len(names)): # if name_edit1 == names[i]: # name_edit2 = input("请输入要修改为的名字：") # names[i] = name_edit2 # print("修改成功！") # else: # print("查无此人") # 法二： find_name = 0 # 默认没找到 for i in range(len(names)): if name_edit1 == names[i]: name_edit2 = input("请输入要修改为的名字：") names[i] = name_edit2 print("修改成功！") find_name = 1 if find_name = 0: print("查无此人") elif num == 3: name_select = input("请输入要查询的名字：") if name_select in names: print("找到了要查找的人") else: print("查无此人") elif num == 4: name_del = input("请输入要进行删除的名字：") if name_del in names: names.remove(name_del) print("删除成功！") else: print("查无此人，无法进行删除") elif num == 5: break else: print("输入错误！") |
小编再为大家分享另一段用python中列表实现名字管理系统的代码：
1、打印功能提示
2、获取用户输入
3、根据用户的输入选择相应的功能进行实现

#打印提示print("="*50)print("names_manage_systme")print("1、add a new name")print("2、delete a name")print("3、modify a name")print("4、search a name")print("5、quit!")print("="*50)#存储用户姓名names = []while True:#获取用户输入 user_input_num = int(input("please input the number you need:"))#功能实现 if user_input_num == 1: #增加 new_name = input("please input the new name that you need to add:") names.append(new_name) print(names) elif user_input_num == 2: #删除 del_name = input("please input the new name that you need to delete:") names.remove(del_name) print(names) elif user_input_num == 3: #改 modify_name = input("please input the new name that you need to modify:") after_modify_name = input("please input the new name :") length = len(names) modify_name_index = 0 i = 0 while i < length: if modify_name == names[i]: modify_name_index = i break i += 1 names[modify_name_index] = after_modify_name print(names) elif user_input_num == 4: #查找 search_name = input("please input the new name that you need to search:") length = len(names) search_name_index = 0 i = 0 while i < length: if search_name == names[i]: search_name_index = i break i += 1 if i == length: search_name_index = -1 #没有找到的话令索引置为-1 print("the index of your search_name is:%d"%search_name_index) elif user_input_num == 5: #退出 print("quit success!") break else: print("input number wrong!\nplease input again") |
