Like yours, they return the original object if unchanged.
that makes me uncomfortable, but I guess as srings are mutable (an may be interned, why not?) Do the other string methods return themselves if there is no change? As for the "required" idea -- an optional keyword only parameter could be useful, but definitely not the default behavior. That would be incompatible with all the other string methods. Though personally, I think I'd still check that a string "follows the rules" I expect outside this function anyway. -CHB -- Christopher Barker, PhD Python Language Consulting - Teaching - Scientific Software Development - Desktop GUI and Web Development - wxPython, numpy, scipy, Cython
