Sort a list of dictionaries by the only dictionary key - Calab - Oct-27-2023 I have the following structure: my_list = [{"Dog": {"sound":"bark"}}, {"Cow": {"sound":"moo"}}, {"Cat": {"sound":"meow"}}]I want to get the following from this structure sorted or unsorted: ["Cat", "Cow", "Dog"] # or ["Dog", "Cow", "Cat"]The following ALMOST gives me what I want, but I'm getting a list of the complete dictionary instead of just the keys: sorted(my_list, key=lambda x: x.keys[0]) [{'Cat': {'sound': 'meow'}}, {'Cow': {'sound': 'moo'}}, {'Dog': {'sound': 'bark'}}]Using Python 2.7, how can I get the list of the first (only) key from each item in my list of dictionaries? RE: Sort a list of dictionaries by the only dictionary key - buran - Oct-27-2023 my_list = [{'Cat': {'sound': 'meow'}}, {'Cow': {'sound': 'moo'}}, {'Dog': {'sound': 'bark'}}] print [d.keys()[0] for d in my_list]
from itertools import chain my_list = [{'Cat': {'sound': 'meow'}}, {'Cow': {'sound': 'moo'}}, {'Dog': {'sound': 'bark'}}] print list(chain(*my_list)) Both snippets are python2
