Question

我试图想出一些能够成为＆＃34; title＆＃34;一串字。它应该大写字符串中的所有单词，除非给定的单词不作为参数大写。但无论如何，仍然会把第一个词大写。我知道如何利用每个单词，但我不知道如何不利用异常。有点迷失在哪里开始，在谷歌上找不到多少。

  def titlemaker(title, exceptions):
      return ' '.join(x[0].upper() + x[1:] for x in title.split(' '))

或

return title.title()

但是我发现在撇号后会把一封信大写，所以我不认为我应该使用它。关于我应该如何考虑异常的任何帮助都很好

示例：titlemaker（＆＃39;一个男人和他的狗＆＃39;，＆＃39; a和＆＃39;）应该返回＆＃39; A Man and His Dog＆＃39;

Answer 1

def titlemaker(title,exceptions):
    exceptions = exceptions.split(' ')
    return ' '.join(x.title() if nm==0 or not x in exceptions else x for nm,x in enumerate(title.split(' ')))

titlemaker('a man and his dog','a and') # returns "A Man and His Dog"

以上假设输入字符串和异常列表在相同的情况下（就像在你的例子中一样），但是在诸如`titlemaker（'a man and his dog'，'a and''之类的东西上会失败）。如果他们可能是混合的情况吗，

def titlemaker(title,exceptions):
    exceptionsl = [x.lower() for x in exceptions.split(' ')]
    return ' '.join(x.title() if nm==0 or not x.lower() in exceptions else x.lower() for nm,x in enumerate(title.split(' ')))

titlemaker('a man and his dog','a and') # returns "A Man and His Dog"
titlemaker('a man AND his dog','a and') # returns "A Man and His Dog"
titlemaker('A Man And His DOG','a and') # returns "A Man and His Dog"

Answer 2

def titleize(text, exceptions):
    return ' '.join([word if word in exceptions else word.title()
                     for word in text.split()]).title()

Answer 3

试试这个：

def titleize(text, exceptions):
    exceptions = exceptions.split()
    text = text.split()
    # Capitalize every word that is not on "exceptions" list
    for i, word in enumerate(text):
        text[i] = word.title() if word not in exceptions or i == 0 else word
    # Capitalize first word no matter what
    return ' '.join(text)

print titleize('a man and his dog', 'a and')

<强>输出：

A Man and His Dog
