Question

我正在尝试创建一个程序来替换句子中的单词，将其翻译成Pig Latin（老师不关心元音，只关注大写字母），我似乎无法使其正常工作。这是我编写的代码。

def PiggySentence():
    sentence=str(input("Please enter the sentence you would like converted 
    to Pig Latin: "))
    sentence.split()
    caps ='ABCDEFGHIJKLMNOPQRSTUVWXYZ'
    for word in sentence:
        if word[0] in caps:
            word = word[1].upper() + word[2:] + word[0].lower() + "ay"

        else:
            word = word[1:] + word[0] + "ay"

    sentence = " ".join(sentence)
    print(sentence)




PiggySentence()

说

Traceback (most recent call last):
   line 18, in <module>
    PiggySentence()
   line 7, in PiggySentence
    word = word[1].upper() + word[2:] + word[0].lower() + "ay"
IndexError: string index out of range

Answer 1

这里的问题是word[2]超出范围，这意味着字符串不够长，无法包含第三个字符。我不确定您希望程序如何处理诸如a之类的小单词，是要跳过它们还是只附加一个ay或其他内容。
在循环中，设置word不会修改原始数组。您可能需要一个输出变量，可以将翻译后的单词添加到该变量，例如：

output = []
for word in sentence:
    if word[0] in caps:
        output.append(word[1].upper() + word[2:] + word[0].lower() + "ay")

    else:
        output.append(word[1:] + word[0] + "ay")

sentence = " ".join(output)

将sentence.split()放在单独的行上并不能满足您的要求，因为它只返回每个字符处拆分的数组。您想要在每个空格处分割后存储返回值，所以您想进行sentence = sentence.split(" ")

Answer 2

首先，您不应该在函数内部进行输入。其次，您不考虑单个字母的单词。修改您的函数以仅当长度大于1时才进行Pig Latin格式化。

这样的事情。

def PiggySentence():
sentence=str(input("Please enter the sentence you would like converted to Pig Latin: "))
sentence.split()
caps ='ABCDEFGHIJKLMNOPQRSTUVWXYZ'
for word in sentence:
    if len(word) > 1:
        if word[0] in caps:
            word = word[1].upper() + word[2:] + word[0].lower() + "ay"

        else:
            word = word[1:] + word[0] + "ay"

sentence = " ".join(sentence)
print(sentence)
