You found an unsafe overlap.
x.thing = x = 1
would work, though it seems strange (and unlikely in practice) to rebind x
to an int after it is bound to a class k instance.
This code is starting to look like it wants to work with a linked list.
class node:
def __init__(self,x):
self.payload=x
self.next=None
def walk(self):
print("My payload is: "+self.payload)
if self.next: self.next.walk()
head=tail=node("This")
tail.next=tail=node("is")
tail.next=tail=node("a")
tail.next=tail=node("test.")
head.walk()
My payload is: This
My payload is: is
My payload is: a
My payload is: test.
Cute. I am used to linked lists being built from the bottem up in
functional languages with immutable nodes. I might even use something
like this. Of course, for a list of any length, walk needs to be iterative.
def walk(self):
while self:
print("My payload is: "+self.payload)
self = self.next
