如何先按键然后按元组值对字典进行排序

Question

Given an input dictionary like

{13: (3,1,7), 2: (6,4,9), 7: (5,8,4)}

get an out put dictionary like

{2: (4,6,9), 7: (4,5,8), 13: (1,3,7)}

Answer 1

From Python 3.6 onwards, dictionaries honor insertion order. You can accomplish what you want by using sorted at the level of both the dict items as well as within the individual values:

>>> dict(sorted((k, tuple(sorted(v))) for (k, v) in a.items()))
{2: (4, 6, 9), 7: (4, 5, 8), 13: (1, 3, 7)}

Answer 2

You can use comprehension.

a = {13: (3,1,7), 2: (6,4,9), 7: (5,8,4)}
sorted_a = {key:tuple(sorted(a[key])) for key in sorted(a)}
