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)))

使用来自Perl的Schwartzian变换，

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

do

sort_on = "name"
decorated = [(dict_[sort_on], dict_) for dict_ in py]
decorated.sort()
result = [dict_ for (key, dict_) in decorated]

给予

>>> result
[{'age': 10, 'name': 'Bart'}, {'age': 39, 'name': 'Homer'}]

在计算机科学中，施瓦茨变换是一种Perl编程用于提高项目列表排序效率的习惯用法。这当排序为实际上基于元素，其中计算该属性是一项密集的操作应执行最少次数。施瓦茨学派Transform的显著之处在于它不使用命名的临时数组。

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)

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｝〕

假设我有一本字典D，其中包含以下元素。要排序，只需使用sorted中的key参数传递自定义函数，如下所示：

D = {'eggs': 3, 'ham': 1, 'spam': 2}
def get_count(tuple):
    return tuple[1]

sorted(D.items(), key = get_count, reverse=True)
# Or
sorted(D.items(), key = lambda x: x[1], reverse=True)  # Avoiding get_count function call

看看这个。
