position of super().__init__() gives different output

Question

I was trying to understand this example working.

class P: 
   def __init__(self): 
      self.__x=100 
      self.y=200 
   def print(self): 
      print(self.__x, self.y)  
class C(P): 
   def __init__(self):
      super().__init__()  <-------------------
      self.__x=300 
      self.y=400
       
        
d = C() 
d.print()

output: 100 400

class P: 
   def __init__(self): 
      self.__x=100 
      self.y=200 
   def print(self): 
      print(self.__x, self.y)  
class C(P): 
   def __init__(self):      
      self.__x=300 
      self.y=400
      super().__init__()   <--------------------
       
        
d = C() 
d.print()

output: 100 200

Can someone explain the execution flow of the above codes leading to separate outputs?
