Question

1.4 Get All Candidates (2 points] Complete and test the function get_all_candidates: • Input: a list . This list can be a list of strings, a list of lists, or a list of dictionaries. Or a mix of all three. • Return: all the unique strings in this list and its nested contents. • Example: >>> get_all_candidates ([{'GREEN' :3, 'NDP':5}, {'NDP':2, 'LIBERAL’:4}, D :2, ’LIBERAL”:47 ’NDP'), 'BLOC ['GREEN', ’NDP', 'LIBERAL', 'CPC', 'BLOC'] ’NDP', 'LIBERAL 1.5 Get Min/Max Candidate (2 points) Complete and test the function get_candidate_by-place: • Input: a dictionary with the format we have from the last four functions, and a function (assume either min or max) • Evaluate the function on the dictionary's values. Return the key of the dictionary corre- sponding to that value. • Put another way: if the function is max, we return the winner of the election. If the function is min, we return the last place candidate. Return the key of the dictionary • Break ties randomly. • Example: >>> result = {'LIBERAL’:4, 'NDP':6, 'CPC':6, 'GREEN’:4} >>> random.seed (0) >>> get_candidate_by_place(result, min) 'GREEN >>> random.seed (1) >>> get_candidate_by_place(result, min) 'LIBERAL' 1.6 Get Winner (1 point] Complete and test the function get_winner: • Input: a dictionary with same format as above • Return the key with the greatest value. If there are ties, break them randomly. • Example: >>> get_winner({'NDP': 2, "GREEN': 1, LIBERAL': 0, 'BLOC': 0}) 'NDP 1.7 Get Last Place [1 point] Complete and test the function last-place: • Input: a dictionary with same format as above • Return the key with the lowest value. If there are ties, break them randomly.

Answer 1

Thanks for the questions, I was not able to understand Question 1.5 as there are some back references with the question which are not included in the post. Need to go through it. 

I have coded the rest of the functions all below with screenshots. Please share the complete details for question 1.5 and will help you out.

thanks.
