Hi i have below class. Please help ans below queries

class SplitData():
    def __init__(self, train, valid): 
      print('splid data')
      self.train,self.valid = train,valid
        
    def __getattr__(self,k): 
      print('__getattr',k)
      return getattr(self.train,k)
   def __repr__(self): return f'{self.__class__.__name__}\nTrain: {self.train}\nValid: {self.valid}\n'
