python取名字最后一个字

使用Here键。

Here是获取Python3中OrderedDict的最后一个键的方法.我需要在Python3中获取OrderedDict的最后一个值,而无需转换为列表.

Python 3.4.0 (default, Apr 11 2014, 13:05:11)

>>> from collections import OrderedDict

>>> dd = OrderedDict(a=1, b=2)

>>> next(reversed(dd))

'b'

>>> next(reversed(dd.keys()))

Traceback (most recent call last):

File "", line 1, in

TypeError: argument to reversed() must be a sequence

>>> next(reversed(dd.items()))

Traceback (most recent call last):

File "", line 1, in

TypeError: argument to reversed() must be a sequence

>>> next(reversed(dd.values()))

Traceback (most recent call last):

File "", line 1, in

TypeError: agument to reversed() must be a sequence
