除了已经提到的方法之外。可以使用" viewitems " " viewkeys " " viewvalues "

>>> d = {320: 1, 321: 0, 322: 3}
>>> list(d.viewitems())
[(320, 1), (321, 0), (322, 3)]
>>> list(d.viewkeys())
[320, 321, 322]
>>> list(d.viewvalues())
[1, 0, 3]

Or

>>> list(d.iteritems())
[(320, 1), (321, 0), (322, 3)]
>>> list(d.iterkeys())
[320, 321, 322]
>>> list(d.itervalues())
[1, 0, 3]

或者使用itemgetter

>>> from operator import itemgetter
>>> map(itemgetter(0), dd.items())     ####  for keys
['323', '332']
>>> map(itemgetter(1), dd.items())     ####  for values
['3323', 232]

一本简单的字典:

x = {'X':"yes", 'Y':"no", 'Z':"ok"}

在Python 3中打印一个特定的(键，值)对(本例中是索引1处的pair):

for e in range(len(x)):
    print(([x for x in x.keys()][e], [x for x in x.values()][e]))

输出:

('X', 'yes')
('Y', 'no')
('Z', 'ok')

下面是打印元组中所有对的一行程序:

print(tuple(([x for x in x.keys()][i], [x for x in x.values()][i]) for i in range(len(x))))

输出:

(('X', 'yes'), ('Y', 'no'), ('Z', 'ok'))

您可以通过在字典上调用items()来访问键和/或值。

for key, value in d.iteritems():
    print(key, value)

打印键值对，例如:

players = {
     'lebron': 'lakers',
     'giannis':   'milwakee bucks',
     'durant':  'brooklyn nets',
     'kawhi':   'clippers',    
}

对于player，在players.items()中的club:

print(f"\n{player.title()} is the leader of {club}")

上面的代码，键值对:

 'lebron': 'lakers', - Lebron is key and lakers is value

对于循环-在dictionary.item()中指定键和值:

现在打印(玩家名是俱乐部队长)。

输出为:

#Lebron is the leader of lakers
#Giannis is the leader of milwakee bucks
#Durant is the leader of brooklyn nets
#Kawhi is the leader of clippers

如果要按字典键对输出进行排序，可以使用集合包。

import collections
for k, v in collections.OrderedDict(sorted(d.items())).items():
    print(k, v)

它适用于python 3

或者，对于Python 3:

for k,v in dict.items():
    print(k, v)
