I have 2 class

```
Class Point:
Def __init __ (Self, X, Y):
Self.x = X.
self.y = y.
DEF DIST (SELF, POINT):
distance = ((self.x - point.x) ** 2 + (self.y - point.y) ** 2) ** 0.5
RETURN DISTANCE
DEF X (SELF):
Return Self.x.
DEF Y (Self):
Return Self.y.
Class Circle (Point):
Def __init __ (Self, R, Point):
Self.r = R.
Self.point = Point
DEF Center (Self):
Return Self.point.
```

I do not understand how to implement such a design to applying the X property of the Radius property of the Circle object, I received the value x, and when referring to y, respectively y. To create an object C1 `C1 = Circle (4, Point (1.5.1)) `

, it was possible to get the X `C1.center.x == 1.5 `

## Answer 1

You have `Center `

is a method. To get a value from it, it is not enough to contact him by name, it still needs **Call **. For this you need to add brackets after his name:

```
c1.center (). X
```

however, there is an alternative. You can use the method of `Property `

method, and then it will start behaving as an ordinary attribute, and it will be possible to call it as you are in the example

```
Class Circle (Point):
Def __init __ (Self, R, Point):
Self.r = R.
Self.point = Point
@property # add this
def center (self):
return self.point
c1 = Circle (4, Point (1.5,1))
print (c1.center.x) # And this option starts
```
