Unable to invoke/call a Python method

can't get my class variables working properly,

class World:
  def __init__(self, size):
    self.size = size
    self.grid = []
    for i in range(0,size):
        self.grid.append([])
        for j in range(0,size):
            self.grid[i].append(0)
  def Display(self):
    for row in self.grid:
        print row

TheWorld = World(int(raw_input("Input world size(integer): ")))
TheWorld.Display

The problem is, the display function doesn't do anything, i think it's not referencing self.grid properly somehow. I input the world size as 0,10,100, doesn't make a difference. Any ideas ?? Thanks

Well that should be because you have not actually called the Display function. You have to say

TheWorld.Display()

for the function to be actually called.

Add braces to call the method:

TheWorld.Display()

This is not VBA. I have to call the function using ():

TheWorld = World(int(raw_input("Input world size(integer): ")))
TheWorld.Display()

You are not calling the function, you are merely referencing the function object. Try:

TheWorld.Display()
