You are right. I played a little with ipython3, which made finding
things out a lot easier. ;-)
In my case it is a script, that terminates very soon after being
finished with p, but it is certainly good practise to do it myself.
I always did a free in my C programming days. I was always told it was
not necessary, but I found it better to do it anyway.
By the way, what also works is:
p = None
But it was just a try in ipython3. I would never do this in real code.
I was just curious if this would be handled correctly and it is. :-)
