I'll start with the obvious:

while submissions > 0:    ...    submissions -= 1

can be transformed into:

for _ in xrange(submissions):    ...

There are other changes that I think would make the code slightly better, albeit not necessarily more pythonic:

• submissions should probably be namedsubmissionCount.
• You appear to be parsing HTML usingstring.split(). It might work OK now, but if you need to add more functionality in the future this approach will be very cumbersome. Try using a library instead (for example,Beautiful Soup).
• You're not using thepprint import, so you might as well remove that line.
