I've been using python as a tool to solve competitive programming problems
for a while now and I've noticed a feature, python would benefit from
having.
Consider "reversed(enumerate(a))". This is a perfectly readable code,
except it's wrong in the current version of python. That's because
enumerate
sense.

Hi all,
I'm in the process of learning Python by writing a job queue program.
Nothing fancy, mind you, just read from a table, shell out to a program,
write back to the table.
I'm working off of the tutorial listed here (amongst many places):

In my Jobs c
inds on its
assigned port.
That was it.
Also changing '127.0.0.1' to 'localhost' solves the problem.
Thanks.

db=MySQLdb.Connect(user="me",passwd="my password",db="test")

Hi all, happy new year,
I was trying to pickle a instance of a subclass of a tuple when I ran
into a problem. Pickling doesn't work with HIGHEST_PROTOCOL. How should
I rewrite my class so I can pickle it?
Thanks ,
