Python 如何划分为两个功能？

对于python的基础计算机科学课程，我们正在编写一个程序，该程序读入一个文件，将该文件翻译成pig拉丁语，并将翻译写入一个新文件，并计算翻译的行数和单词数

file_path = raw_input("Enter a file pathway: ")
f_input = file(file_path, "r")
f_output = file("pig_output.txt","w")

vowels = ("a","e","i","o","u","A","E","I","O","U")


def piglat_trans():
    line_count = 0
    word_count = 0
    for line in f_input:
        words = line.split(" ")
        pig_line = ""
        line_count += 1
        for word in words:
            word = word.strip("\n")
            word_count += 1
            if word[0] in vowels:
                pig_word = word + "way"
            elif word[0] not in vowels and word[1] not in vowels and len(word)>1:
                pig_word = word [2:len(word)] + word[0] + word[1] + "ay"
            else:
                pig_word = word[1:len(word)] + word[0] + "ay"
            pig_line += pig_word + " "
        f_output.write(pig_line + "\n")
    print "Translation finished and written pig_output.txt"
    print "A total of " + str(line_count) + " lines were translated successfully."
    print "A total of " + str(word_count) + " words were translated successfully."


piglat_trans()

f_input.close()
f_output.close()

该程序运行良好，但我应该使行/字计数和打印部分与转换器本身的功能分离。我该怎么做

谢谢你的帮助！ **编辑：另外，我在翻译时遇到空格和制表符的问题，它返回：

line 25, in piglat_trans if word[0] in vowels:
IndexError: string index out of range

既然这是一个家庭作业，我就不写代码了

看起来您的关键逻辑位于最内部的for循环中，在该循环中，您获取一个单词并将其拼音化

然后，您只需要一个映射器函数，将源代码中的每个单词映射到文本的拉丁版本。此函数还可以计算行数

并且，尝试使您的文件处理程序短命，并使用上下文管理器（

和Python中的

语句）

下面是我要做的：

def pigify(word):
    ....
    return pig

def pigify_text(text):
    ...
    pig_words = map(pigify, words)
    ...
    return (pig_text, word_count, line_count)

with open(infile) as f:
    text = f.read()

pig, wc, lc = pigify_text(text)

with open(outfield, "w") as f:
     f.write(pig)

print wc
print lc

对于最后一个错误，请考虑<代码> 'B'。拆分（“”）< /代码>将返回<代码> [a，'，' b' ] < /代码>；您可能希望只使用

.split（）

而不带参数。
