I keep getting various parse errors like

    Expected assignment, comment or return statement but " " found.

When trying to get rid of parse errors, I did something like "return x" and it says

    Solution did not return correct output for x=1. Expected output: 1, got: 0

Which is clearly not right.

Just tried doing "return 1" and still got

    Solution did not return correct output for x=1. Expected output: 1, got: 0
