Doubt about del statement in Python

If a string variable is deleted with the del statement, what happens to the string contained in the now deleted variable?

del deletes the reference. When the value is garbage-collected (deleted), depends on the implementation. It may be erased right away or later – given that the data is not referenced otherwise, of course. https://stackoverflow.com/a/1481512

I never found the need to del a string variable. Using del on a variable makes it invalid unless a new value is assigned to it. Python is garbage collected, so memory allocation and deallocation is abstracted away. The more common use of del is for list items. courses = ["Python","Java","C++"] del courses[1]
