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

Treehouse TeacherHi Eva Feng,
I see the issue — lines 10 to 14 need to be indented. Python is very particular about indentation, and right now, your init and repr methods are not part of the Node class because they’re aligned at the same level as the class definition.
Once you indent lines 10 to 14 so they’re inside the class, the error should go away.
