[BangPypers] Reorder Dictionary Size in python

[Rahul R]

As far as i know, python performs a lazy deletion of values , when we
delete content from a dictionary (correct me if i am wrong) .  So, when we
insert a lot of values the dictionary automatically expands. I don't see
dict shrinking when we delete values from dictionary. In such case, is
there a way to forcibly reduce the dictionary size ?
