Question

我正在尝试在python中构建一个英语到猪拉丁语的转换程序。我的程序成功将所有英语单词转换为Pig Latin单词。但我不明白如何将标点符号放在猪拉丁语句中的同一位置，就像在原始英语句子中一样。我转换了标点符号，无论是在单词的最后一位还是第一位，但是我无法转换像撇号（＆＃39; s）这样的单词之间的标点符号或者像问号（？）一样的两个标点符号。句子关闭单/双引号（＆＃39; /＆＃34;）等。这是我的代码：

import string
import random
def take_input(sentence):
    prefix=[]
    stem=[]
    word_ans=[]
    punc=[]
    sent_ans=[]
    for word in sentence.split():
        word=list(word)
        for i in range(len(word)):
            if word[i] in ('A','E','I','O','U','Y','a','e','i','o','u','y'):
                stem=word[i:]
                break
            else:
                prefix.append(word[i])
        for x in stem:
            word_ans.append(x)
        for x in prefix:
            word_ans.append(x)
        word_ans.append('a')
        word_ans.append('y')
        if word[-1] in string.punctuation:
            word_ans.remove(word[-1])
            word_ans.append(word[-1])
        if word[0] in string.punctuation:
            word_ans.remove(word[0])
            word_ans[1:]=word_ans
            word_ans[0]=word[0]
        for i in word_ans:
            sent_ans.append(i)
        sent_ans.append(' ')
        del prefix[:]
        del stem[:]
        del word_ans[:]
    sent_answer=''.join(sent_ans)
    return sent_answer
Answer=take_input("'Hi, How are you?'")
print Answer

期望的输出：＆＃39; iHay，owHay areay youay？＆＃39;

当前输出：我＆＃39; Hay，owHay areay you？ay＆＃39;

Answer 1

你最好的选择是使用正则表达式：

import re
text = 'Hi, how are you? I am fine.'
tokens = re.split("(\W)", text)
pig_tokens = map(lambda t: t if not re.search('\w', t) else t[-1].upper() + t[:-1].lower() + 'ay', tokens)
print ''.join(pig_tokens) # Ihay, Whoay Earay Uyoay? Iay Maay Efinay.
