Which command would you use to delete an entire dictionary?

The command used to delete an entire dictionary in Python is "del dictionary_name." This command removes the specified dictionary from memory, meaning that the variable name that referred to the dictionary will no longer be valid, and trying to access it afterward will result in an error.

Deleting a dictionary using this command effectively clears all references to the dictionary and frees up the memory it was using. It is important to note that this action is irreversible; once the dictionary is deleted, all the key-value pairs it contained are also lost.

The other options do not perform the same function. For instance, "delete" and "remove" are not valid Python commands for deleting a dictionary; Python does not recognize these terms in this context. Moreover, the "clear" method is used to remove all items from the dictionary but retains the dictionary itself. The dictionary would still exist as an empty dictionary after using "clear," rather than being completely deleted from memory.
