Question

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?

Answer 1

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.'
