Tell us what’s happening:

I’m having a problem with passing the second test I think I’ve fulfilled all the needed steps but this test won’t complete. please tell me if there is anything wrong that might be causing this test to fail.

Your code so far

the test asks you to do this:

you should print Unexpected format '<key>: <val>' at position <index>. (where <key> , <val> , and <index> should be replaced by the current key, value and index) inside your for loop.

@Drewlius is pointing out that you should be using the variable names, not the values stored in the variables.

@dhess thank you for translating that to a more concise explanation :right_facing_fist::left_facing_fist:
