I don't understand generator.send()

n? In my code I was hoping to get 0,1,2,3,4,5,2,6,7 as yield expressions. Victor. -- Victor Eijkhout -- eijkhout at tacc utexas edu -- http://mail.python.org/mailman/listinfo/python-list

long int computations

I have two long ints, both too long to convert to float, but their ratio is something reasonable. How can I compute that? The obvious "(1.*x)/y" does not work. Victor. -- Victor Eijkhout -- eijkhout at tacc utexas edu -- http://mail.python.org/mailman/listinfo/python-list
