私が取り組んでいるプログラムに問題があります。これは、都市シミュレーターになることを目的としています。最初の 2 行は機能しますが、その後は機能しません。コードは以下です。何が間違っているのかわかりません。

>>> ================================ RESTART ================================
>>> 
Welcome to SIM
This is a text based city simulator.
Traceback (most recent call last):
  File "C:/Python33/SIM.py", line 102, in <module>
    Turn()
  File "C:/Python33/SIM.py", line 25, in Turn
    money = money + moneyPerTurn
UnboundLocalError: local variable 'money' referenced before assignment

moneyグローバル スコープで として定義していますが、Turn()関数ではそれをグローバルとして宣言していません。次のようにする必要があります。

money = 2000
moneyPerTurn = population * 5

def Turn ():
    global money
    global moneyPerTurn
    money = money + moneyPerTurn
    print('STATUS REPORT')

では、 がグローバル変数Turnを参照することを宣言する必要があります。moneymoney

def Turn ():
    global money
    money = ........

現在、python は関数でmoney定義された変数を探していますTurnが、存在しません。キーワードはglobal、変数をグローバル スコープから のスコープに「インポート」しますTurn。
