Was reading the official python document and I noticed they mentioned queues
being more efficient for adding/removing elements vs list so I wrote a quick
test the validate this claim and I wasn't very impressed by the results it
seems queues are just slightly faster so my question to the list, is
p=[]
if p is None:
... print 'yes'
...
This doesn't work as expected.
