首先，split关闭第一个词：

first, rest = title.split(None, 1)

现在，检查第一个单词是否是文章：

if first in {'A', 'An', 'The'}:

如果是这样，请将其移至末尾：

    return rest + ', ' + first

把它们放在一起：

def fix_title(title):
    first, rest = title.split(None, 1)
    if first in {'A', 'An', 'The'}:
        return rest + ', ' + first
    return title

---

如果您希望能够正确处理空行，则需要更多逻辑，我认为在这种情况下，使用partition而不是split. 只需将中间的两行更改为：

    first, _, rest = title.partition(' ')
    if first in {'A', 'An', 'The'} and rest:
