You could subclass UserString instead of str; all of UserString's methods seem to ensure that instances of the subclass rather than just plain strs or UserStrings are returned. See http://docs.python.org/library/userdict.html#UserString.UserString
I'll have a look at it, thanks
But you should also consider whether your additions absolutely *must* be methods. Merely instead defining some functions that take strings as parameters is obviously a simpler, and probably more performant, approach.
I regularly save web pages (mostly scientific research abstracts) from various web sites and use a python script to strip them of ads and unneeded informations, embedding the images directly in the html file (as base64 encoded data) and at times joining multiple pages into just one
since those sites often change the format of their files I've to modify my script accordingly
I'm already using plain functions, but thought that wrapping most of them in a str subclass would let me save some time and yield cleaner and more manageable code
If you insist on subclassing str, there's no such hook; you'll have to override all the methods yourself.*
I'll try this route too (at least for the methods I need) thanks for your help -- bye !(!1|1) -- http://mail.python.org/mailman/listinfo/python-list
