from operator import itemgetter
# if you would like to play with multiple dictionaries then here you go:
# Three dictionaries that are composed of first name and last name.
user = [
    {'fname': 'Mo', 'lname': 'Mahjoub'},
    {'fname': 'Abdo', 'lname': 'Al-hebashi'},
    {'fname': 'Ali', 'lname': 'Muhammad'}
]
#  This loop will sort by the first and the last names.
# notice that in a dictionary order doesn't matter. So it could put the first name first or the last name first. 
for k in sorted (user, key=itemgetter ('fname', 'lname')):
    print (k)

# This one will sort by the first name only.
for x in sorted (user, key=itemgetter ('fname')):
    print (x)

如果你知道你所有的键都是相同的类型，或者有支持'< '(小于，python的__lt__)的类型，那么你可以使用dict(sorted(your_dict.items()， key=lambda _: _[0]))一个容易理解的一行程序

伙计们，你们把事情搞复杂了……非常简单

from pprint import pprint
Dict={'B':1,'A':2,'C':3}
pprint(Dict)

输出结果为:

{'A':2,'B':1,'C':3}

from operator import itemgetter
# if you would like to play with multiple dictionaries then here you go:
# Three dictionaries that are composed of first name and last name.
user = [
    {'fname': 'Mo', 'lname': 'Mahjoub'},
    {'fname': 'Abdo', 'lname': 'Al-hebashi'},
    {'fname': 'Ali', 'lname': 'Muhammad'}
]
#  This loop will sort by the first and the last names.
# notice that in a dictionary order doesn't matter. So it could put the first name first or the last name first. 
for k in sorted (user, key=itemgetter ('fname', 'lname')):
    print (k)

# This one will sort by the first name only.
for x in sorted (user, key=itemgetter ('fname')):
    print (x)

有一个简单的方法:

d = {2:3, 1:89, 4:5, 3:0}

s = {k : d[k] for k in sorted(d)}

s

Out[1]: {1: 89, 2: 3, 3: 0, 4: 5} 

就问题的表述方式而言，这里的大多数答案都是正确的。

然而，考虑到事情应该如何真正完成，考虑到几十年的计算机科学，让我完全惊讶的是，这里实际上只有一个答案(来自GrantJ用户)建议使用排序关联容器(sortedcontainers)，它基于插入点的键对元素进行排序。

这将避免每次调用sort(…)时对性能的巨大影响(至少O(N*log(N))，其中N是元素的数量(逻辑上，这适用于这里建议使用sort(…)的所有此类解决方案)。考虑到对于所有这样的解决方案，sort(…)将需要在每次通过添加/删除元素修改后，当需要以排序方式访问集合时调用…
