python中有没有一种字符串方法可以将首字母缩略词大写？

这很好：

import string
string.capwords("proper name")

Out: 'Proper Name'

这不太好：

string.capwords("I.R.S")

Out: 'I.r.s'

是否没有字符串方法来进行大写字母以便可以容纳首字母缩略词？

原文

This is good:

import string
string.capwords("proper name")

Out: 'Proper Name'

This is not so good:

string.capwords("I.R.S")

Out: 'I.r.s'

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

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."

This might work:

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)

Here is a test:

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."
