python中的Pig拉丁字符串转换答案

【问题标题】：Pig latin string conversion in pythonpython中的Pig拉丁字符串转换
【发布时间】：2020-07-13 21:14:07
【问题描述】：

我正在尝试创建一个将文本转换为猪拉丁语的函数：简单的文本转换，它修改每个单词，将第一个字符移动到末尾并将“ay”附加到末尾。但我得到的只是一个空列表。有什么建议吗？

def pig_latin(text):
  say = ""
  words = text.split()
  for word in words:
    endString = str(word[1]).upper()+str(word[2:])
    them = endString, str(word[0:1]).lower(), 'ay'
    word = ''.join(them)
    return word

print(pig_latin("hello how are you")) # Should be "ellohay owhay reaay ouyay"
print(pig_latin("programming in python is fun")) # Should be "rogrammingpay niay ythonpay siay unfay"

【问题讨论】：

您要返回单词而不是单词吗？无论如何它可能会破裂
为什么要拆分say而不是text？
我不确定我是否理解这个问题。如果我返回 word 我得到一个错误：第 13 行错误：print(pig_latin("hello how are you")) # 应该是 "ellohay owhay reaay ouyay" 第 11 行错误：返回 word UnboundLocalError: local variable 'word' referenced分配前
在我看来，您可能在第三行拆分了错误的字符串。您不是打算将字符串变量“文本”拆分为“单词”，而不是空字符串“说”吗？
@emremrah 因为说是我要拆分的字符串不是吗？如果我拆分文本，我会得到：你很有趣

【解决方案1】：

def pig_latin(text):
  words = text.split()
  pigged_text = []

  for word in words:
    word = word[1:] + word[0] + 'ay'
    pigged_text.append(word)

  return ' '.join(pigged_text)

print(pig_latin("hello how are you"))

输出：ellohay owhay reaay ouyay

其实我的回答几乎和@ventaquil 一样，我没注意到。由于他/她首先回答，您可以选择他/她的答案作为接受的答案。

我试过了，它对我有用


def pig_latin(text):
  say = []

  # Separate the text into words

  words = text.split()
  for word in words:

    # Create the pig latin word and add it to the list

    word = word[1:] + word[0] + "ay"
    say.append(word)

    # Turn the list back into a phrase

  return " ".join(say)

print(pig_latin("hello how are you")) # Should be "ellohay owhay reaay ouyay"

print(pig_latin("programming in python is fun")) # Should be "rogrammingpay niay ythonpay siay unfay"

为我工作

def pig_latin(sentence):
    output = []
    for word in sentence.split(" "):
        word = word[1:] + word[0] + "ay"
        output.append(word)
    return " ".join(output)

只需对每个单词使用列表理解，然后将它们重新组合在一起。

编辑：此解决方案存在多个空格的问题，例如当人们在 colon: ! 之后放置两个空格时

def dowork(sentence):

    def pigword(word):
        return "".join([word[1:], word[0], "ay"])

    return " ".join([pigword(word) for word in sentence.split()])


dataexp = [
    ("hello how are you","ellohay owhay reaay ouyay"),
    ("programming in python is fun","rogrammingpay niay ythonpay siay unfay")
    ]

for inp, exp in dataexp:
    got = dowork(inp)
    msg = "exp :%s:  for %s \n      got :%s:" % (exp, inp, got)
    if exp == got:
        print("good! %s" % msg)
    else:
        print("bad ! %s" % msg)

输出

good! exp :ellohay owhay reaay ouyay:  for hello how are you
      got :ellohay owhay reaay ouyay:
good! exp :rogrammingpay niay ythonpay siay unfay:  for programming in python is fun
      got :rogrammingpay niay ythonpay siay unfay:

为什么需要嵌套函数？ ' '.join([x[1:]+x[0]+'ay' for x in 'hello world'.split()])
好吧，它不必嵌套。但我喜欢把它变成自己的功能来分离关注点。各有各的。

这是一个适用于我的解决方案：

   def pig_latin(text):
      # Separate the text into words
        words = text.split()
        #creating a new empty list called pig
        pig=[]
        # creating a for loop to alter every word in words
        for word in words:
            
            """here we are assigning the altered word to a new variable pigged_word. The we can remove first word alone from the original word usin
                indexing and add/concat the letter at zeroth index (1st letter) back to the
                    word and add/concat new string 'ay' at end """
            
            pigged_word=word[1:]+word[0]+'ay'
            #append the altered words to the list
            # use append instead of insert since you can add word to end of list
            pig.append(pigged_word)
            #now convert it back to 
        return (' '.join(pig))
            
    print(pig_latin("hello how are you")) # Should be "ellohay owhay reaay ouyay"
    print(pig_latin("programming in python is fun")) # Should be "rogrammingpay niay ythonpay siay unfay"

请尝试理解问题并解决。拆分 say 变量是行不通的，理想情况下，您必须将文本拆分成几部分，即使那样您也不必与 " "

拆分

基于 Herman Singh 的回答，但省略了创建一个空列表并在 for 循环中附加到它的反模式（这样称呼它可能有点强）。

def pig_latin(text):
    words = [
        word[1:] + word[0] + "ay"
        for word in text.split()
    ]
    return " ".join(words)


print(pig_latin("hello how are you"))  # Should be "ellohay owhay reaay ouyay"
print(pig_latin("programming in python is fun"))  # Should be "rogrammingpay n

这可以简化为一行，但我认为它不利于可读性。

def pig_latin(text):
    return " ".join([word[1:] + word[0] + "ay" for word in text.split()])


print(pig_latin("hello how are you"))  # Should be "ellohay owhay reaay ouyay"
print(pig_latin("programming in python is fun"))  # Should be "rogrammingpay siay unfay

只需使用列表推导即可实现紧凑性和简单性：

’ ‘.join([word[1:] + word[0] + ‘ay’ for word in text.split(‘ ‘)])

    say += pig_word

使用以下代码：

def pig_latin(texts):
    return ' '.join([text.replace(text[0],'') + text[0]+'ay' for text in texts.split()])

print(pig_latin("hello how are you"))
print(pig_latin("programming in python is fun"))

会得到想要的结果：

ellohay owhay reaay ouyay
