Anyone with an interest in the string functions vs. string methods debate should read this article, which was referenced in comp.lang.python recently:
How Non-Member Functions Improve Encapsulation by Scott Meyers http://www.cuj.com/archive/1802/feature.html
Mr. Meyers presents some very well-reasoned arguments against the everything-should-be-a-method mentality.
Note that the motivation for turning to string methods was that of migrating from strings to Unicode. Adding Unicode support to the strop C module would have caused very complicated code -- methods helped by enabling polymorphic code which is one of the great advantages of writing software for an interface rather than an implementation. Note that functions can make very good use of methods and thus implement polymorphic functionality -- this is not about methods vs. functions it's about methods to enable polymorphic functions. -- Marc-Andre Lemburg ______________________________________________________________________ Company: http://www.egenix.com/ Consulting: http://www.lemburg.com/ Python Pages: http://www.lemburg.com/python/
