[sage-support] Nested if statements inside sum

Hi, I want to make a function for a sum that has two different options for each term, depending on a condition. E.g. F(m) = sum(n=1, 10, if( m*n0, m*n+2, m*n+8)) How do I put the else if m*n0 then m*n+8 into the Sage statement: sum( m*n +2 for n in range(1,10) if m*n0 ) ? Thank you Kim --

One option is: sage: def F(m): :return sum([(m*n+2 if m*n 0 else m*n+8) for n in range(1, 10)]) sage: F(2) 162 sage: F(-2) -72 --Mike -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to
