New beginner, defining point help :(

Beside unindenting class definition you need to unindent both ToString methods, and your test code, so it would look like:

class Point():
   def __init_(self, x, y):
       ....
   def ToString(..
        ....
class Circle(Point):
   def __init__(...
       ...
   def ToString(..
       ....

p = Point ...

Morever you need to use __init__(double underscore) instead of _init_.
