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)

for key, value in d.iteritems():
    print key, '\t', value

对于Python 3.x

for key, value in d.iteritems():
    print(f'{key}\t{value}') 

或者，对于Python 3:

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

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)

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]

>>> d={'a':1,'b':2,'c':3}
>>> for kv in d.items():
...     print kv[0],'\t',kv[1]
... 
a   1
c   3
b   2
