Your error is because your attempting to reverse your function.. What you want to do is reverse your list INSIDE your function ----------------------------- def TenToOne(n): n.reverse() return n TenToOne([1,2,3,4,5,6,7,8,9]) ----------------------------- Let's Break It down.. line #1 - Define our function and set a variable "n" to hold our list when we call the function line #2 - Reverse our list which we assigned to n line #3 - Return n as our reversed list line #4 - Call the function and assign our list as variable n

if your using the function I wrote, you use it like this TenToOne([1,2,3,4,5,6,7,8,9]) if you want to print that or store it to a variable you can do so like this backward=TenToOne([1,2,3,4,5,6,7,8,9]) print(backward) or directly print like this print(TenToOne([1,2,3,4,5,6,7,8,9]))

THIS IS HOW YOU WRITE THE FUNCTION def TenToOne(n): n.reverse() return n THIS IS HOW YOU CALL YOUR FUNCTION TenToOne([1,2,3,4,5,6,7,8,9])
