Question

create a function that takes a dictionary and returns a list of int. The list should appear in decreasing order based on the sum of number in each dictionary.

def total_num(dict1):

#Code here

input = {1: {'una': 5, 'dos': 7, 'tres': 9, 'quar' : 11}, 2: {'dos':2, 'quar':3}, 3:{'una': 3, 'tres': 5}, 4:{'cin': 6}, 5:{'tres': 7 , 'cin': 8}}

output = [1,5,3,4,2]

1: 38

2: 5

3: 8

4: 6

5: 15

1>5>3>4>2

Answer 1

def total_num(dict1):
    items = list(sorted(dict1.items(), key=lambda x: sum(x[1].values()), reverse=True))
    result = []
    for k, v in items:
        result.append(k)
    return result


# Testing the function here. ignore/remove the code below if not required
input = {1: {'una': 5, 'dos': 7, 'tres': 9, 'quar': 11}, 2: {'dos': 2, 'quar': 3}, 3: {'una': 3, 'tres': 5},
         4: {'cin': 6}, 5: {'tres': 7, 'cin': 8}}
print(total_num(input))
