Create a dictionary that has keys 2,3,5,7,11 each of which has a value that is an empty list. Look at the list of number, and append each number to the lists of the keys that evenly divide the number. You can loop over a dictionary keys using 'for k in dict' / 'for k in dict.keys()' without quotes.

e.g. Given a list [6,30] the 6 would be appended to the d[2] and d[3]. 30 would be appended to d[2], d[3], and d[5]. etc.

WARNING Codingbat has issues with formatting so you have to return a list with your dictionary inside of it. You must return [D] where D is your dictionary.
