python - When I create an object, what do I pass as the arguments? -


i have class/function in file named "worldmodel.py":

import entities import pygame import ordered_list import actions import occ_grid import point  class worldmodel:    def __init__(self, num_rows, num_cols, background):       self.background = occ_grid.grid(num_cols, num_rows, background)       self.num_rows = num_rows       self.num_cols = num_cols       self.occupancy = occ_grid.grid(num_cols, num_rows, none)       self.entities = []       self.action_queue = ordered_list.orderedlist()   def add_entity(world, entity):    obj = occ_grid.grid()    pt = entities.get_position(entity)    if within_bounds(world, pt):       old_entity = occ_grid.get_cell(pt)       if old_entity != none:          entities.clear_pending_actions(old_entity)       obj.set_cell(pt, entity)       world.entities.append(entity)

and have class/method in file named "occ_grid.py":

# define occupancy value empty = 0 gatherer = 1 generator = 2 resource = 3  class grid:    def __init__(self, width, height, occupancy_value):       self.width = width       self.height = height       self.cells = []        # initialize grid specified occupancy value       row in range(0, self.height):          self.cells.append([])          col in range(0, self.width):             self.cells[row].append(occupancy_value)     def set_cell(self, point, value):       self.cells[point.y][point.x] = value

if on first line of code in body of def add_entity, see i've created object can use set_cell, method occ_grid.py. i'm not sure pass occ_grid.grid() arguments. feedback/thoughts appreciated!

from def __init__(self, width, height, occupancy_value), can see self, width, height , occupancy_value need passed.

now, self put there need pass in other 3 so:

occupancy_value = # whatever initial value want cells have width = # whatever width want height = # whatever height want obj = occ_grid.grid(width, height, occupancy_value)
