如何从字典中删除？

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

# 删除键为"key2"的键值对
del my_dict["key2"]

print(my_dict)

{"key1": "value1", "key3": "value3"}

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

# 删除键为"key2"的键值对，并返回被删除的值
deleted_value = my_dict.pop("key2")

print(my_dict)
print(deleted_value)

{"key1": "value1", "key3": "value3"}
"value2"
