How about providing a sum function that would behave like, say, the integrate function. It could detect the argument types so if you passed it a list, it'd behave the same as the builtin sum function.
sage: integrate(x, x, 0, 10) 50 sage: sum(x, x, 0, 10) 55 sage: sum(range(10)) 45 I'm having trouble thinking of other instances where range() not including the upper bound would cause (major) problems. --Mike On 9/18/07, Jaap Spies <[EMAIL PROTECTED]> wrote: > > Robert Bradshaw wrote: > > >> Why not define a new function srange (short for sagerange), > >> or redefine the existing srange function: > >> > >> def srange(a,b=None,step=1, include_endpoint=True): > >> > >> or something like that. > >> > >> See sage: srange?? > >> > >> Alternative: reuse xrange > >> this function will be removed from Python in Python3000. > > > > One disadvantage of this is that include_endpoint=True takes much > > more time to write than "+1", and requires the same amount of > > knowledge.
