Node and linked list

Hi this is my code below:

class Node: data = None next_node = None

def init(self, data): self.data = data

def repr(self): return "<Node: data: %s>" % self.data

However when I run the console:

python -i linked_list.py

it says

Traceback (most recent call last): File"<stdin>, line 1, in <module> Type error: Node() takes no arguments
