用句子中的数字替换单词[重复]

Question

我的句子中有时将数字写成单词，例如：

He takes classes of yoga two times per week.

我需要用数字替换写成单词的数字：

He takes classes of yoga 2 times per week.

如果是He takes classes of yoga twice per week.，则应保持原样。

我找到了一个名为 word2number 的库，可以将单词转换为数字 (link)。但是如何更新一个句子得到He takes classes of yoga 2 times per week.？

from word2number import w2n

w2n.word_to_num('He takes classes of yoga two times per week.')
# output: 2

Answer 1

这应该处理任意多字数。它不会处理句尾标点符号，例如“野兽的数量是六百六十六。”。你可能想先去掉标点符号。我想句子中间的逗号也会发生同样的情况。

def translate(sentence):
    result = []
    partial = []
    for word in sentence.split():
        partial.append(word)
        num = w2n.word_to_num(' '.join(partial))
        # If this worked, then go try to suck up another word.
        if num:
            continue
        # If there's more than one word in partial, then all but the
        # last make a successful number.
        if len(partial) > 1:
            result.append( w2n.word_to_num(' '.join(partial{[:-1]) ))
        result.append( word )
        partial = []
    return ' '.join(result)
