Is there a way to convert number words to Integers

Question

I need to convert one into 1, two into 2 and so on.

Is there a way to do this with a library or a class or anything?

Answer 1

Here's the trivial case approach:

>>> number = {'one':1,
...           'two':2,
...           'three':3,}
>>> 
>>> number['two']
2

Or are you looking for something that can handle "twelve thousand, one hundred seventy-two"?
