Error in my assignment c2 w1

error in my assignment
can u help me

It looks like you modified the template code for that function. The return statement no longer returns any values, which is why the variable parameters (which is assigned with the return value of the function) ends up being “None”. Here’s what that statement looks like in a clean copy of the notebook:

    return parameters

So why did you change that?

If you want to get a clean copy of the notebook to make sure there is not more damage like this, there is a topic about that on the DLS FAQ Thread.

Oooh thanks
I did it by mistake
