I think weve had all these discussions recently.

Start here:

Conclusion: the "missing methods" might get implemented, if someone
gets round to it.  THe unicode string type has more methods (it has
center, ljust, rjust).

Start here:

Conclusion: nothing obvious, but the status quo seems the most likely
(& best - to me) winner.

No, but they ways that always worked still work <wink>:

>>> dir('')
['capitalize', 'center', 'count', 'endswith', 'expandtabs', 'find',
'index', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper',
'join', 'ljust', 'lower', 'lstrip', 'replace', 'rfind', 'rindex',
'rjust', 'rstrip', 'split', 'splitlines', 'startswith', 'strip',
'swapcase', 'title', 'translate', 'upper']
>>> dir(u'')
['capitalize', 'center', 'count', 'encode', 'endswith', 'expandtabs',
'find', 'index', 'isdecimal', 'isdigit', 'islower', 'isnumeric',
'isspace', 'istitle', 'isupper', 'join', 'ljust', 'lower', 'lstrip',
'replace', 'rfind', 'rindex', 'rjust', 'rstrip', 'split',
'splitlines', 'startswith', 'strip', 'swapcase', 'title', 'translate',
'upper']
>>> ''.__methods__
['capitalize', 'center', 'count', 'endswith', 'expandtabs', 'find',
'index', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper',
'join', 'ljust', 'lower', 'lstrip', 'replace', 'rfind', 'rindex',
'rjust', 'rstrip', 'split', 'splitlines', 'startswith', 'strip',
'swapcase', 'title', 'translate', 'upper']

No, no capwords.
