Sorting a dictionary of pairs based on value-CodePudding

I have the code

mydict = {"layer1" : { 0: 0.765}, 'layer2': {0: 0.9876}}
for idx in range(5):
   mydict['layer1'][idx] = idx   900
   mydict['layer2'][idx] = idx   800
sorted_x = sorted(mydict.items(), key=lambda kv: kv[1])

it gives the error

TypeError: '<' not supported between instances of 'dict' and 'dict'

when I type

sorted_x = sorted(mydict.items(), key=lambda kv: kv[2])

it gives the error

IndexError: tuple index out of range

it onley works for index 0 which is a string!

I want the dictionary to be sorted based on the value and give the results like

[('layer2', {0: 800, 1: 801, 2: 802, 3: 803, 4: 804}), ('layer1', {0: 900, 1: 901, 2: 902, 3: 903, 4: 904})]

what should I do?

CodePudding user response：

Here is a simple change you can put in your code:

Change

sorted_x = sorted(mydict.items(), key=lambda kv: kv[1])

to:

sorted_x = sorted(mydict.items(), key=lambda kv: kv[1][1])
