Python 猪拉丁文转换器

Question

请帮帮我！

我正在把一个包含多行的文本文件转换成猪拉丁语。

举个例子：这句话 "This is an example." 转换成猪拉丁语后应该是 "Histay siay naay xampleeay."

我需要保留标点符号，通常是在句子的结尾。

另外，任何在原文中以大写字母开头的单词，在猪拉丁语中也要以大写字母开头，其余的字母要小写。

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!

然后程序返回：

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

我该如何让它们按照原来的行打印出来？还有，我该如何处理标点符号和大小写的问题？

Answer 1

我负责处理所有的工作，除了标点符号。我还在考虑一个解决方案。这是我的代码：

def convert_file(fileName):
    inputFile = open(fileName,'r')
    punctuations = ['.',',','!','?',':',';']
    newWords = []
    linenum = 1

    for line in inputFile:
        line_string  = line.split()
        for word in line_string:
            endString= str(word[1]).upper()+str(word[2:])
            them=endString, str(word[0:1]).lower(), 'ay'
            word = ''.join(them)
            wordAndline = [word,linenum]
            newWords.append(wordAndline)
        linenum +=1
    return newWords

这个代码的不同之处在于，它会返回单词和它在文件中的行数。

['Histay', 1], ['Siay', 1], ['Naay', 1], ['Xample.eay', 1], ['Ymay', 3], ['Amenay', 3], ['Siay', 3], ['Ara!kay', 3]

这是我对你代码的改进。你应该考虑使用 nltk 这个库。它在处理单词分割方面要强大得多。

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
