I've been playing with the binomial function, and found that in the below code, rs *= x does not behave the same way as rs = rs * x. When I set FAIL to True, I get a different result. Both results are below. I had read that the two were equivalent. What am I missing? thanks, -= miles =- #!

Precedence, d'oh! rs *= (n-(i-1))/i is equivalent to: rs = rs * ((n-(i-1))/i) not rs = rs * (n-(i-1))/i which is the same as rs = ( rs * (n-(i-1)) ) /i Ken Iverson was right. Precedence is a bad idea. -- https://mail.python.org/mailman/listinfo/python
