Which command would you use to remove a key from a dictionary?

The command that correctly removes a key from a dictionary in Python is formulated using the del statement. By employing the syntax del dictionary["key"], you can effectively delete the specified key and its associated value from the dictionary. This method is straightforward and works well when you need to permanently remove the key-value pair from the dictionary.

When using del, if the specified key does not exist in the dictionary, it will raise a KeyError, alerting the programmer that the key to be deleted is not found.

Other options involve functions or methods that are not valid or do not accomplish the task of removing a key directly. For instance, a method like remove does not exist for dictionaries, as it is specific to list objects. The use of delete as a command in Python is incorrect as well, since it does not belong to the Python language syntax for dictionary manipulation. The pop method of a dictionary is an alternative way to remove a key, and it does allow for the retrieval of the value associated with the key being removed. However, it is not the same as using del, as it combines removal with accessing the value, making del the more direct answer for this question.
