If there isn't a better alternative, I would welcome a new index() function/method in the next numpy release.Without commenting on the desirability of this particular function, people seem awfully eager to add functions and methods everywhere. These aren't free you know. They cost in terms of maintenance and potential bugs, and in terms of making the already large function set even harder to wrap ones head around. There is already a need to thoughtfully weed out the existing namespace. from X import * is deprecated by some. Colin W. That's partly an organizational problem but partly an issue of sheer size, neither of which are helped by adding a bunch more stuff. Not every two-line Python function has to come pre-written --Tim Peters In the case of this particular function, what are the use cases? Are they common (not just with you but with other numpy users)? Are the uses speed critical? Is it a good building block for other numeric functions? I'm skeptical of the above implementation as it doesn't fit well with other similar numpy functions (argmin and argmax for example) and I personally don't see much in the way of compelling uses for this, but feel free to try to convince me otherwise. -tim ------------------------------------------------------------------------- Using Tomcat but need to do more?
