Python has a type for a 'dictionary', which is basically a set of key-value pairs, as well as a common ADT (abstract data type). We give an 'example'. grades = {'jo':55, 'moe':97, 'will':74, 'bill':80)} Here are some messages and their outcomes: grades.keys() ['jo','moe','will','bill'} grades.values() [55,97,74,80] grades.items() [('jo',55),('moe',97),('will',74),('bill',80)] NOTE: the above approximates python syntax, but the output format is intended to be suggesive only.
