快速解决方案是使用inflect.py生成翻译字典。
inflect.py有一个number_to_words()函数，它会将一个数字（例如2）转换为它的单词格式（例如'two'）。不幸的是，它没有提供它的反向（这将允许你避免翻译字典路由）。同样，您可以使用该函数来构建翻译词典：
>>> import inflect
>>> p = inflect.engine()
>>> word_to_number_mapping = {}
>>>
>>> for i in range(1, 100):
... word_form = p.number_to_words(i) # 1 -> 'one'
... word_to_number_mapping[word_form] = i
...
>>> print word_to_number_mapping['one']
1
>>> print word_to_number_mapping['eleven']
11
>>> print word_to_number_mapping['forty-three']
43
如果您愿意花一些时间，可以检查一下number_to_words()函数的inflect.py的内部工作原理并构建自己的代码来动态执行此操作（我没有尝试过这一点）。
