本文实例讲述了python实现将英文单词表示的数字转换成阿拉伯数字的方法。分享给大家供大家参考。具体实现方法如下：

import re

_known = {

'zero': 0,

'one': 1,

'eight': 8,

'nine': 9,

'ten': 10,

'eleven': 11,

'twelve': 12,

'thirteen': 13,

'fourteen': 14,

'fifteen': 15,

'sixteen': 16,

'seventeen': 17,

'sixty': 60,

'seventy': 70,

'eighty': 80,

'ninety': 90

}

def spoken_word_to_number(n):

"""Assume n is a positive integer".

assert _positive_integer_number('nine hundred') == 900

assert spoken_word_to_number('one hundred') == 100

assert spoken_word_to_number('eleven') == 11

assert spoken_word_to_number('nineteen eighty nine') == 1989

assert spoken_word_to_number('one thousand nine hundred and eighty nine') == 1989

assert spoken_word_to_number('nine eighty') == 980

assert spoken_word_to_number('nine two') == 92 # wont be able to convert this one

assert spoken_word_to_number('nine thousand nine hundred') == 9900

assert spoken_word_to_number('one thousand nine hundred one') == 1901

"""

n = n.lower().strip()

if n in _known:

return _known[n]

inputWordArr.append('zero')

if inputWordArr[-1] == 'thousand':

inputWordArr.append('zero')

inputWordArr.append('zero')

inputWordArr.append('zero')

if inputWordArr[0] == 'hundred':

inputWordArr.insert(0, 'one')

if inputWordArr[0] == 'thousand':

inputWordArr.insert(0, 'one')

inputWordArr = [word for word in inputWordArr if word not in ['and', 'minus', 'negative']]
