Question

Stuck on PS8, Problem 2. Question is: Do you convert the subjects dictionary into a list before applying the optimization algorithms? If not, how do you find the subject name (the dictionary key), based on the (work, value) pair (the dictionary value)?

Answer 1

[key for key, value in dictionary.iteritems() if value == (work, value)]
should return a list of keys whose values meet the criteria.

you get to decide whether to work with the dictionary or with lists. there are a number of ways to solve these.

if you use dictionary methods to get lists of the keys and values, the order of the two lists are guaranteed to be maintained
