グローバルvarialbeが、私は、変数の定義/エラーから持っ以前

Question

コードに定義されたものの：

def preFight(): 
    global enemy 
    enemynum=random.randint(1,3) 
    if enemynum==1: 
     enemy=goblinIG

     win() 
    os.system('clear')

    option=raw_input("")

#def store() 


main() 

戦いが開始したとき、私は取得していますエラーは次のとおりです。

Traceback (most recent call last): 
    File "/home/ubuntu/workspace/rpg_game.py", line 194, in <module> 
    main() 
    File "/home/ubuntu/workspace/rpg_game.py", line 46, in main 
    start() 
    File "/home/ubuntu/workspace/rpg_game.py", line 60, in start 
    start1() 
    File "/home/ubuntu/workspace/rpg_game.py", line 75, in start1 
    preFight() 
    File "/home/ubuntu/workspace/rpg_game.py", line 93, in preFight 
    enemy==skeletonIG 
NameError: global name 'enemy' is not defined 

これは、私が敵を定義し、グローバルとして設定するので、私を混乱させます。誰かが私が問題の原因を見つけるのを助けてくれるでしょうか？

Answer 1

あなたはこの機能の代入でエラーがあります。=に対し、平等のための==チェックが代入演算子なので

def preFight(): 
    global enemy 
    enemynum=random.randint(1,3) 
    if enemynum==1: 
     enemy=goblinIG 
    elif enemynum==2: 
     enemy=zombieIG 
    elif enemynum==3: 
     enemy==skeletonIG 
    fight() 

enemy==skeletonIGは、enemy=skeletonIGでなければなりません。
