Hi Just wondering, would anyone think of it as a good idea if the enumerate() builtin could accept a "start" argument? I've run across a few cases where this would have been useful. It seems generic enough too.

+1, but something more useful might be a a cross between enumerate a zip, where you pass N iterables and it yields N-tuples. Then you could do something like: zipyield(range(10, 20), mygenerator()) and it would be like you wanted for enumerate, but starting from 10 in this case. -Michel

All of this already exists. from itertools import izip, count for i,j in izip(count(start), iterable): ... Read your standard library. - Josiah

And why not an additional "step" argument? Anyway, perhaps all this can be done with a 'xrange' object... -- Lisandro Dalcín --------------- Centro Internacional de Métodos Computacionales en Ingeniería (CIMEC) Instituto de Desarrollo Tecnológico para la Industria Química (INTEC) Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) PTLC - Güemes 3450, (3000) Santa Fe, Argentina Tel/Fax: +54-(0)342-451.1594
