Hi! Everytime your program calls function p, list1 is appended to. It keeps on getting bigger and bigger. The function adds all the elements of the list, but the total is divided by 1000, even if the list is already much longer that 1000! And there's another thing. When var1 and var2 are intege

Re: [Tutor] Unexpected Result in Test Sequence

When you declare list1 before "def p()" you are making it global. That means it will keep its values between invocations of p(). When you start function p, you don't reset list1 to empty. You divide each time by 1000, and but your list1 list is growing and growing and growing. That's why the total
