I edited this because I need more help. How do you check if c is blank? Is c is simply equal to []?

I've tried ==[] and "[]" and getting the length and == "", but nothing seems to work.

In python, an empty list evaluates to False.

if not c:    print "The list is empty" else:    print "The list is not empty"
