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

Python 2和Python 3

I是键，所以你只需要使用它:

for i in d:
    print i, d[i]

Python 3

D.items()返回迭代器;要获得一个列表，需要自己将迭代器传递给list()。

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

Python 2

你可以得到一个同时包含键和值的迭代器。D.items()返回一个(key, value)元组列表，而d.iteritems()返回一个提供相同元组的迭代器:

for k, v in d.iteritems():
    print k, v

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}')

from rich import print

prices = {
    "banana": 4,
    "apple": 2,
    "orange": 1.5,
    "pear": 3,
    "strawberry": 1,
    "blueberry": 0.5,
    "mango": 4.5
}

print(prices)
