Reference Count
sys.getrefcount() method is used to get the reference count for any given object. This value is used by Python as when this value becomes 0, the memory for that particular value is deleted.
Example:
This code prints the reference count of the object a. The reference count of an object is the number of times it is referenced by other objects. An object is garbage collected when its reference count reaches 0, meaning that it is no longer referenced by any other objects
Python3
import sysa = 'Geeks'print(sys.getrefcount(a)) |
