在python中，有没有一种字符串方法来大写首字母缩写词？

Question

这很好：

import string string.capwords("proper name") 'Proper Name'

这不太好：

string.capwords("I.R.S") 'I.r.s'

有没有字符串方法来做capwords以便它能容纳缩略词？在

Answer 1

这可能有用：

import re

def _callback(match):
    """ This is a simple callback function for the regular expression which is 
        in charge of doing the actual capitalization. It is designed to only 
        capitalize words which aren't fully uppercased (like acronyms).
    """
    word = match.group(0)
    if word == word.upper():
        return word
    else:
        return word.capitalize()

def capwords(data):
    """ This function converts `data` into a capitalized version of itself. This 
        function accomidates acronyms.
    """
    return re.sub("[\w\'\-\_]+", _callback, data)
