Oops, try again. Remember: len(list_name) will return the length of a list as an integer.
suitcase =  suitcase.append("sunglasses") # Your code here! suitcase.append('shirt') suitcase.append('bathing suit') suitcase.append('pants') list_length = 4 # Set this to the length of suitcase print "There are %d items in the suitcase." % (list_length) print suitcase
