You can use vars() to create the variables on the fly. vars() is just a 
dictionary containing the variable name as the key, and the data as the 
value so you can do `vars()['list1'] = []` and it's easy enough to 
create them en masse

# Set the start to 1, and add 1 to what the user inputted
# as range/xrange doesn't include the top number
for i in xrange(1, user_input + 1):
     vars()['list%s' % i] = []

Hope that helps.
