Posted 2020-09-04

dict = [
{‘id‘:‘4‘,‘name‘:‘b‘},
{‘id‘:‘6‘,‘name‘:‘c‘},
{‘id‘:‘3‘,‘name‘:‘a‘},
{‘id‘:‘1‘,‘name‘:‘g‘},
{‘id‘:‘8‘,‘name‘:‘f‘}
]
dict_b = sorted(dict, key=lambda a:a[‘id‘])
print dict_b

排序后：[{‘id‘: ‘1‘, ‘name‘: ‘g‘}, {‘id‘: ‘3‘, ‘name‘: ‘a‘}, {‘id‘: ‘4‘, ‘name‘: ‘b‘}, {‘id‘: ‘6‘, ‘name‘: ‘c‘}, {‘id‘: ‘8‘, ‘name‘: ‘f‘}]
