computer_move（）は引数を2つ（3つ）指定しますか？

Question

import random 
#these will be the positions the computer will take 
new = ['', '', '', '', '', '', '', '', ''] 
null = '' 
#string for the player 
player = '' 
#string for the computer 
computer = '' 

ここでは、ユーザー（player）とコンピュータの2つのチームを定義します。だから、それが唯一の可能

def computer_move(computer, new): 

：

move_c = computer_move(player, computer, new) 

しかし、機能は以下のように定義されていますcomputer_firstとplayer_first機能インサイド

Answer 1

は、次の3つの引数でcomputer_moveを呼び出そうとしています3つではなく2つの引数で呼び出されます。
