大写时保留段落标记 - RegEx
Preserve paragraph marks while capitalzing - RegEx
p = re.compile(r'((?<=[\.\?!]\s)(\w+)|(^\w+))')
def cap(match):
return(match.group().capitalize())
capitalized_1 = p.sub(cap, Inputfile)
with codecs.open('o.txt', mode="w", encoding="utf_8") as file:
file.write(capitalized_1)
我正在使用 Regex 将 . 之后的字母大写。 ？ ！上面的代码就是这样做的。但是它去掉了段落标记（page break pilcrow）并将其合并为一个大段落。
如何保留段落标记并防止结块？

on the insert tab, the galleries include items that are designed to coordinate with the overall look of your document. you can use these galleries to insert tables, headers, footers, lists, cover pages, and other document building blocks. when you create pictures, charts, or diagrams, they also coordinate with your current document look.
you can easily change the formatting of selected text in the document text by choosing a look for the selected text from the quick styles gallery on the home tab. you can also format text directly by using the other controls on the home tab. most controls offer a choice of using the look from the current theme or using a format that you specify directly.
