suitcase = 
list_length = 4 # Set this to the length of suitcase
print "There are %d items in the suitcase." % (list_length)
Oops, try again. Remember: len(list_name) will return the length of a list as an integer.
I have no clue why this would be wrong, unless you would need to fill something in, in the top brackets??? The error message makes no sense to me because it never tells you to use the len function. Any help would be appreciated. Thanks
