Question

Is garbage collection done in Python by itself or do we need to do it ourselves.
I used to believe that Python used to manage all sort of memory issues itself and we need worry about memory management.

The reason I am asking this is because I saw gc module in Python documentation
http://docs.python.org/library/gc.html

If memory management is handle by itself then whats the point of this module.

Answer 1

Quoting the link provided in the question:

Since the collector supplements the reference counting already used in Python, you can disable the collector if you are sure your program does not create reference cycles.

It seems clear enough.
