Python OOP broken? - jfelten - 06-23-2021 08:51 PM
Whenever I try to call a class method, the interpreter sometimes doesn't recognize that the "self" parameter is implied. most of my tests worked fine, but one certain case gave me an error:
Code:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "main.py", line 5, in <module>
File "game.py", line 20, in __init__
TypeError: initialize() takes 1 positional arguments but 0 were given(In case you're wondering, I am trying to recreate the popular board game Risk.)
Here is my code so far:
main.py:
Code:
import player
import game
from hpprime import *
Game=game.RGame()
fillrect(0,0,0,320,240,0x90c0ff,0x90c0ff)
blit(0,0,0,2)
"""
for p in Game.players:
p.initialize()
"""game.py:
Code:
import player
from hpprime import *
class RGame():
def __init__(self):
eval('G2:=AFiles("board.png")')
self.playerCount=3
self.multiplayer=False
startTroops=[40,35,30,25][self.playerCount-2]
self.players=[]
for i in range(self.playerCount):
if self.multiplayer==True or self.playerCount==0:
self.players.append(player.HumanPlayer)
else:
self.players.append(player.HumanPlayer)
p=self.players[-1]
p.troopsToDeploy=startTroops
p.initialize()
self.players[-1]=p
print(str(p))
def render(self):
fillrect(0,0,0,320,240,0x90c0ff,0x90c0ff)
blit(0,0,0,2)player.py:
Code:
class Player():
def __init__(self, id):
self.id=None
self.occTerritories=[]
self.TroopsToDeploy=0
def __str__(self):
return "id: "+str(self.id)+"\nTroops to deploy: "+str(self.TroopsToDeploy)
def placeTroops(self):
pass
def initialize(self):
self.placeTroops()
class HumanPlayer(Player):
def __init__(self):
self.object_variable= 1
def placeTroops(self):
print("place your troops")Is it a problem with my code, the interpreter, or both?

You might need to create a class instance:
self.players.append(player.HumanPlayer())
