是否有一种字符串方法可在python中将首字母缩写大写？ [英] is there a string method to capitalize acronyms in python?

问题描述

这很好：

导入字符串
字符串.capwords（专有名称）
'专有名称'

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

这不是很好：

string.capwords （ IRS）
'Irs'

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

是否没有字符串方法可以用来写单词，所以它可以容纳首字母缩写词？

Is there no string method to do capwords so that it accomodates acronyms?

推荐答案

这可能有效：

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)

这是一个测试：

print capwords("This is an IRS test.")    # Produces: "This Is An IRS Test."
print capwords("This is an I.R.S. test.") # Produces: "This Is An I.R.S. Test."
