python猪拉丁转换器

Question

请帮我！

我正在将多行文本文件转换为猪拉丁文。

示例：Pig的拉丁语翻译：这是一个示例。应该是：Histay siay naay xampleeay。

我需要将标点符号留在原处（大多数情况下是句子的结尾）。我还需要任何以原始字母大写字母开头，以猪拉丁字母大写字母开头的单词，以及其余的字母小写。

这是我的代码：

def main():
    fileName= input('Please enter the file name: ')

    validate_file(fileName)
    newWords= convert_file(fileName)
    print(newWords)


def validate_file(fileName):
    try:
        inputFile= open(fileName, 'r')
        inputFile.close()
    except IOError:
        print('File not found.')


def convert_file(fileName):
    inputFile= open(fileName, 'r')
    line_string= [line.split() for line in inputFile]

    for line in line_string:
        for word in line:
            endString= str(word[1:])
            them=endString, str(word[0:1]), 'ay'
            newWords="".join(them)
            return newWords

我的文本文件是：

This is an example.

My name is Kara!

程序返回：

Please enter the file name: piglatin tester.py
hisTay
siay
naay
xample.eay
yMay
amenay
siay
ara!Kay
None

我如何让他们按照他们所在的行打印？另外，我该如何处理标点符号和大写字母呢？

这是我对您的代码的修改。您应该考虑使用nltk。它具有更强大的单词标记化处理。

def main():
    fileName= raw_input('Please enter the file name: ')

    validate_file(fileName)
    new_lines = convert_file(fileName)
    for line in new_lines:
        print line

def validate_file(fileName):
    try:
        inputFile= open(fileName, 'r')
        inputFile.close()
    except IOError:
        print('File not found.')

def strip_punctuation(line):
    punctuation = ''
    line = line.strip()
    if len(line)>0:
        if line[-1] in ('.','!','?'):
            punctuation = line[-1]
            line = line[:-1]
    return line, punctuation

def convert_file(fileName):
    inputFile= open(fileName, 'r')
    converted_lines = []
    for line in inputFile:
        line, punctuation = strip_punctuation(line)
        line = line.split()
        new_words = []
        for word in line:
            endString= str(word[1:])
            them=endString, str(word[0:1]), 'ay'
            new_word="".join(them)
            new_words.append(new_word)
        new_sentence = ' '.join(new_words)
        new_sentence = new_sentence.lower()
        if len(new_sentence):
            new_sentence = new_sentence[0].upper() + new_sentence[1:]
        converted_lines.append(new_sentence + punctuation)
    return converted_lines
