I think you want is > if y_1 = y_2: > y_1 = y_2 = 2 > elif y_1>y_2: > y_1 = y_2 = 1 "[a,b] = x" essentially means "tmp = list(x); a = tmp[0]; b = tmp[1]" > x=0 > for y_1 in [1..2]: > for y_2 in [1..y_1]: > x += [y_1,y_2] > print x What are you trying to do here? x is an integer, [y_1, y_2] is a list of integers. It doesn't really make sense to add an integer to a list. > The error messages I am getting is " TypeError: > 'sage.rings.integer.Integer' object is not iterable ". > > When this code is fixed and does work, the answer would be x=5. > Can anybody see where my code is going wrong please? > > Kind Regards > Chappman > > -- > To post to this group, send email to sage-support@googlegroups.com > To unsubscribe from this group, send email to > sage-support+unsubscr...@googlegroups.com > For more options, visit this group at > http://groups.google.com/group/sage-support > URL: http://www.sagemath.org -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
