快速循环遍历整个python字典的方法

my_dict = {"key1": "value1", "key2": "value2", "key3": "value3"}

for key in my_dict:
    print(key, my_dict[key])

my_dict = {"key1": "value1", "key2": "value2", "key3": "value3"}

for key, value in my_dict.items():
    print(key, value)

my_dict = {"key1": "value1", "key2": "value2", "key3": "value3"}

for key in my_dict.keys():
    print(key, my_dict[key])

my_dict = {"key1": "value1", "key2": "value2", "key3": "value3"}

for value in my_dict.values():
    print(value)
