Hi @ayman!!
Thank you for reaching out to the Educative Team. Here, you need to create a class node in order to proceed with the task. To do so, you can start by defining the class with the keyword “class” followed by the class name, like this:

class Node:

From there, you can add any attributes or methods that are needed for your program. If you need further guidance or have any other questions, please don’t hesitate to let us know. We’re here to help!
Happy Learning :blush:
