It sounds like you may have an error in the definition of the __init__ method in class Node.

If you need help with finding it, share your workspace with us so we can take a look.
Here's a video about sharing a snapshot of your workspace.

When I run your code in the workspace, I get no errors. Exactly how are you running it?

By typing the following in console: python -i linked_list.py

and error message will show up saying Node() takes no arguments. Could it be the set up of my PC?
