This doesn't work: sum(binomial(8,k),k,0,8)
It says "Either m or x-m must be an integer." But this works: f(n)=sum(binomial(n,k),k,0,8); f(8) and so does this (h/t Rob Beezer): sum([binomial(8,k) for k in range(0,9)]) I don't know if this is a "bug" but it certainly is odd and undesirable behavior. -- David -- To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
