It looks like you're on one of the later tasks, but I don't see the code for the other tasks here. The challenge instructions include this notice: "Important: In each task of this code challenge, the code you write should be added to the code from the previous task." What that means is that you should leave the code you create for each task as-is, and put the code for the next task below it.

When the validator checks your work, it also re-checks all the tasks you did before.

Then, for the "courses" task, remember that iterating through a dictionary returns only the keys, so to access the value instead of "re.value()" you would use "real[re]".

And check the indentation. Anything that is part of a loop must be indented more than the loop statement itself.
