how to make return(self.res) not to output the content of list ?

[luofeiyu]

You could write a separate method that just calls self.grow() and does 
not return the result, and call that method instead from the interactive 
interpreter.

how can i change your meaning into python code?

There is my code structure.

class status():
      def grow(self):
          self.res=  a data ananlyse process
          return(self.res)

     def display(self):
          #to display it in the html table
