Thanks! I'm fairly new to programming and have only used Python 2 so that'll be why :D

I had the same problem. The problem is with the range(1,10) bit.
If you replace that with list(range(1,10)) or [1,2,3,4,5,6,7,8,9] it should work!

because range is a generator (in py 3), so you should have used list(range...) == [...]

I figured it out...
Does anybody know why range(1,10) is not considered to be the same as [1,2,3,4,5,6,7,8,9]?

When I run my code in Powershell it passes the test cases, giving the expected responses.
But when I try to run tests in the console it tells me I'm getting 'Try again' instead of 'Finished' D:

Any advice?

I have the same problem in Python!
On my computer my code returns 9991 with the corresponding values, but on here it's returning []
