How to access a specific value in a list within a dictionary?-CodePudding

upatients = {
    'Junipero':[ 37, 114, 'M', 'I', 6, 2],
    'Sunita':[22, 27, 'F', 'B', 9, 5],
    'Issur':[ 38, 48, 'D', 'W', 4, 1],
    'Luitgard':[ 20, 105, 'M', 'L', 1, 4],
    'Rudy':[ 20, 27, 'D', 'O', 9, 5],
    'Ioudith':[ 19, 93, 'D', 'I', 4, 3]
}

for key in upatients:
    patients = key
    print(patients)

I am trying to access the values in the [5] position in the list and sort the list based on those values. I am having trouble printing those values.

CodePudding user response：

Use the key option to sorted() to use an element of the value when sorting.

def sort_dict_keys(d, index):
    return sorted(d, key = lambda p: d[p][index])

print(sort_dict_keys(upatients, 5))

CodePudding user response：

To print the item at the 5th index in each list you can use:

for key in upatients:
    patients = upatients[key]
    print(patients[5])

Here is one way of getting a sorted list of patients:

tmp = [(upatients[key][5], key) for key in upatients]
sort(tmp)
new_list = [x[1] for x in tmp]
print(new_list)

Output:

['Issur', 'Junipero', 'Ioudith', 'Luitgard', 'Rudy', 'Sunita']
