文章目录1. List 操作2. JSON 操作3. Dict 操作下面是分别演示list、json、dict操作1. List 操作my_list[]# List 操作示例my_list[1,2,3,apple,True]# 添加元素my_list.append(new item)# [1, 2, 3, apple, True, new item]# 修改元素my_list[1]banana# [1, banana, 3, apple, True, new item]# 删除元素my_list.remove(banana)# [1, 3, apple, True, new item]# 列表长度lengthlen(my_list)# 5# 遍历列表foriteminmy_list:print(item)2. JSON 操作importjson# 字典转 JSON 字符串my_dict{name:Alice,age:30,is_student:False}json_strjson.dumps(my_dict,indent4,ensure_asciiFalse)# {name: Alice, age: 30, is_student: false}print(json_str)# JSON 字符串转字典json_str{name: Alice, age: 30, is_student: false}my_dictjson.loads(json_str)# {name: Alice, age: 30, is_student: False}print(my_dict)3. Dict 操作# Dict 操作示例my_dict{name:Alice,age:30,is_student:False}# 访问元素namemy_dict[name]# Alice# 修改元素my_dict[age]31# {name: Alice, age: 31, is_student: False}# 添加键值对my_dict[city]New York# {name: Alice, age: 31, is_student: False, city: New York}# 删除键值对delmy_dict[is_student]# {name: Alice, age: 31, city: New York}# 遍历字典forkey,valueinmy_dict.items():print(f{key}:{value})
