What is the method to access values in a nested diction…

To access values from a nested dictionary, you can use multiple keys to access the elements of the dictionary step by step. Here are some commonly used methods:

1. Can you please explain that to me in simpler terms?

   Can you break that down for me in simpler language?

my_dict = {
    "key1": {
        "key2": {
            "key3": "value"
        }
    }
}

value = my_dict["key1"]["key2"]["key3"]
print(value)  # 输出: "value"

1. retrieve
2. retrieve
3. obtain
4. retrieve

my_dict = {
    "key1": {
        "key2": {
            "key3": "value"
        }
    }
}

value = my_dict.get("key1").get("key2").get("key3")
print(value)  # 输出: "value"

Note: The above methods assume that all keys in the nested dictionary exist. If a key in the nested dictionary does not exist, all the above methods will raise a KeyError exception. To avoid this exception, you can use the get() method and set an appropriate default value.
