Python: maximum recursion depth exceeded while calling a Python object when calling copy function

Question

I have a class Particle which has some parameters and attributes, as you can see below. But, when it does get to the function setter for position, and it executes t

Answer 1

It looks like you're trying to use position as the name of both the property and the ordinary attribute backing it. For example,

@position.setter
def position(self, newPosition):
    self.position = newPosition.copy()
#   ^^^^^^^^^^^^^^^

This attempt to set self.position will use the setter you're defining! Similarly,

@property
def position(self):
    return self.position

This getter just calls itself!

Trying to use self.position inside the position property definition won't bypass the property. If you want a "regular" attribute backing the property, call it something else, like self._position or something.
