error in creating a linked list using python

I am new to data structures.Tried to create a linkled list with a print function,but when running the program it is throwing an error stating "add_link takes one positional argument but 2 were given".Below is the code.Please help me out. thanks in advance

class node:
    def __init__( self ,value, Next = None):
        self.value = value
        self.Next = None
        newnode = None
    
    def add_link(self,data):
         if(self.Next == None):
              self.Next = node(data)
              newnode = self.Next
         else:
             newnode.Next = node(data)
             newnode = newnode.Next
    
    def print(self):
        if(self.Next !=None):
            print(self.node)
            self.next.print()

 # main         
link = node(10)

link.add_link(20)

link.add_link(30)

link.add_link(40)

link.print()

>Solution :

You need to add self as an argument to the add_link() function:

def add_link(self, data):
     if(self.Next == None):
          self.Next = node(data)
          newnode = self.Next
     else:
         newnode.Next = node(data)
         newnode = newnode.Next
