Python language-center of a circle using OOP

Question

class Point:

    def __init__(self, initX, initY):
        \"\"\" Create a new point at the given coordinates. \"\"\"
        self.x = initX
        self.y = initY

            


        

Answer 1

Both getX and getY are methods in your code, not attributes. So you will need to call them using getX() and getY().

So ma=(p2.getY-p1.getY)/(p2.getX-p1.getX) becomes:

ma = (p2.getY()-p1.getY())/(p2.getX()-p1.getX())

And so on, the other code changes.

Otherwise, you can also define your methods as @property:

class Point:
    ...
    ...
    @property
    def getX(self):
        return self.x
    @property
    def getY(self):
        return self.y
    ...

And now you can access these as p1.getX and p2.getY and so on.

Note that the above @property decorator turns the method into a getter, which makes sense to use only with private variables (variables defined to start with _).

As such, since both x and y are normal attributes of your class, you can access them directly without using and property decorators or using getter methods, like p1.x and p2.y, as @Padraic points in his post.
