Remove the last print() call. Then, instead of text[0] , pass text[0].lower() to .find() and see the output.

This is the line of code which you started this step with:

index = alphabet.find(text[0])

You should not remove alphabet.find() but should instead pass text[0] qualified with the lower() method, so that you are searching for a lower case letter in your alphabet string.

This is because, in the previous step, the uppercase letter ‘H’ could not be found in alphabet, and the find() method accordingly returned a value of -1.
