在python中，如何在字典中找到特定的键值对？

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

for key, value in my_dict.items():
    if key == "key2" and value == "value2":
        print("找到了特定的键值对：", key, value)
        break

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

if my_dict.get("key2") == "value2":
    print("找到了特定的键值对：", "key2", my_dict.get("key2"))

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

result = [(key, value) for key, value in my_dict.items() if key == "key2" and value == "value2"]
if result:
    print("找到了特定的键值对：", result[0])
