Python Python Basics Functions and Looping Raise an Exception

I get a Boomer that I don't understand

When I open the preview to see my mistake and the error type, it says an inconsistence use of spaces and tabs. The problem is my code appears to be fine in my point of view. Thanks for helping

def suggest(product_idea):
    return product_idea + "inator"
    if len("product_idea") <= 3:
        raise ValueError
except ValueError:

That kind of error cannot be "seen". It means that the indentation in the code has been done using spaces and tabs. Python allows you to use either, but only one or the other in any particular file.

You have a few other issues here as well:

  • the test and raise must be done before the return
  • variable names should never be enclosed in quotes
  • the instructions only ask you to raise the exception, you won't need an "except" statement

First off, you are returning a result before the code runs, which means the code won't actually run. The return should always be at the end. You also don't need to have another exception at the end of the code outside of the definition of the function. Lastly, you are passing in product_idea in the len function as a string which does not need to happen.

Thank you
