Python’s del statement is used to delete variables and objects in the Python program. Iterable objects such as user-defined objects, lists, set, tuple, dictionary, variables defined by the user, etc. can be deleted from existence and from the memory locations in Python using the del statement. The 2 reasons for using the del statement are – The first is to remove elements from dicts and lists by index; for lists, you can also delete a slice. The second reason is to unbind a variable. Deleting a variable has no greater impact on memory use than changing the value to None.
