问题描述

我想创建一个真实的字典:一个荷兰语到英语字典,含有以下单词:
def reversTranslation(dictionary):

 >>> dictionary = {'tension':['spanning'],'voltage':['spanning','voltage']} 
>>> dictionary = reverseTranslation(dictionary)
>>>字典
{'spanning':['tension','voltage'],'voltage':['voltage']}

如你所见,荷兰语跨越有两种不同的英文含义。
帮助将不胜感激。

解决方案

你去:



$ d
return dict((v1,[k for k,v in d.iteritems()if v1 in v])
for v1 in set(sum(d.values(),[])))


I want to create a "real" dictionary: a Dutch to English dictionary with the following words: def reversTranslation(dictionary):

>>> dictionary= {'tension': ['spanning'], 'voltage': ['spanning', 'voltage']}
>>> dictionary= reverseTranslation(dictionary)
>>> dictionary
{'spanning': ['tension', 'voltage'], 'voltage': ['voltage']}

As you can see in dutch 'spanning' has two different meanings in English. Help will be appreciated.

解决方案

Here you go:

def reverseTranslation(d):
    return dict((v1,[k for k,v in d.iteritems() if v1 in v])
                for v1 in set(sum(d.values(),[])))
