In Creating function with a parameter both the exercises are the same.
Thanks for reaching out.
If you are referring to the two Exercise Notebook files, then pay attention that one of them is for Python 2, while the other one is for Python 3.
If, instead, you are referring to the content of the exercise, note that one of the tasks is about printing a value, while the other one is for returning a value. Also, the mathematical operations associated with each task are different.
Hope this helps.
