my_dict = {"name": "John", "age": 25, "city": "New York"}

# 遍历字典的键
for key in my_dict:
    print(key)

name
age
city

my_dict = {"name": "John", "age": 25, "city": "New York"}

# 遍历字典的值
for value in my_dict.values():
    print(value)

John
25
New York

my_dict = {"name": "John", "age": 25, "city": "New York"}

# 遍历字典的键值对
for key, value in my_dict.items():
