使用Pandas包是另一种方法，尽管其大规模运行时比其他人提出的更传统的方法慢得多：

import pandas as pd

listOfDicts = [{'name':'Homer', 'age':39}, {'name':'Bart', 'age':10}]
df = pd.DataFrame(listOfDicts)
df = df.sort_values('name')
sorted_listOfDicts = df.T.to_dict().values()

下面是一个小列表和一个大（100k+）的字典列表的一些基准值：

setup_large = "listOfDicts = [];\
[listOfDicts.extend(({'name':'Homer', 'age':39}, {'name':'Bart', 'age':10})) for _ in range(50000)];\
from operator import itemgetter;import pandas as pd;\
df = pd.DataFrame(listOfDicts);"

setup_small = "listOfDicts = [];\
listOfDicts.extend(({'name':'Homer', 'age':39}, {'name':'Bart', 'age':10}));\
from operator import itemgetter;import pandas as pd;\
df = pd.DataFrame(listOfDicts);"

method1 = "newlist = sorted(listOfDicts, key=lambda k: k['name'])"
method2 = "newlist = sorted(listOfDicts, key=itemgetter('name')) "
method3 = "df = df.sort_values('name');\
sorted_listOfDicts = df.T.to_dict().values()"

import timeit
t = timeit.Timer(method1, setup_small)
print('Small Method LC: ' + str(t.timeit(100)))
t = timeit.Timer(method2, setup_small)
print('Small Method LC2: ' + str(t.timeit(100)))
t = timeit.Timer(method3, setup_small)
print('Small Method Pandas: ' + str(t.timeit(100)))

t = timeit.Timer(method1, setup_large)
print('Large Method LC: ' + str(t.timeit(100)))
t = timeit.Timer(method2, setup_large)
print('Large Method LC2: ' + str(t.timeit(100)))
t = timeit.Timer(method3, setup_large)
print('Large Method Pandas: ' + str(t.timeit(1)))

import operator
a_list_of_dicts.sort(key=operator.itemgetter('name'))

“key”用于按任意值排序，“itemgetter”将该值设置为每个项的“name”属性。

这是另一种通用解决方案——它按键和值对dict的元素进行排序。

它的优点是不需要指定键，如果某些字典中缺少一些键，它仍然可以工作。

def sort_key_func(item):
    """ Helper function used to sort list of dicts

    :param item: dict
    :return: sorted list of tuples (k, v)
    """
    pairs = []
    for k, v in item.items():
        pairs.append((k, v))
    return sorted(pairs)
sorted(A, key=sort_key_func)

您可以使用以下选项：

lst = [{'name': 'Homer', 'age': 39}, {'name': 'Bart', 'age': 10}]
sorted_lst = sorted(lst, key=lambda x: x['age']) # change this to sort by a different field
print(sorted_lst)

如@Claudiu对@monojohnny在本回答的评论部分所示，给出：

list_to_be_sorted = [
                      {'name':'Homer', 'age':39}, 
                      {'name':'Milhouse', 'age':10}, 
                      {'name':'Bart', 'age':10} 
                    ]

按关键字“age”、“name”对词典列表进行排序（如SQL语句ORDER BY age，name），可以使用：

newlist = sorted( list_to_be_sorted, key=lambda k: (k['age'], k['name']) )

或者，同样

import operator
newlist = sorted( list_to_be_sorted, key=operator.itemgetter('age','name') )

打印（新列表）

〔｛‘name’：‘Bart’，‘age’：10｝，｛‘ame’：‘Milhouse’，‘age’：10〕，｛‘name’：‘Homer’，‘age’：39｝〕
