Python - 「在分配之前引用的本地x變量」（CLOSED）

Question

我遇到了一個我的python程序問題，並且我花了太多時間嘗試修復它，但是我不能。我希望你能幫助我。

無論如何，問題是：

def choose_winnerPvsP(p1,p2): 

當我運行播放器的一部分VS電腦炒鍋完美，但玩家對玩家的一部分給了我這個錯誤：「局部變量player_1score轉讓前參考「 我不明白爲什麼if不會被檢查。 PS：我是一個初學者，我知道代碼可以更緊湊，但現在我只想要這個東西工作。在此先感謝

Answer 1

呃。調試器被高估 - 我在Python中使用了多年，而沒有使用它。只需添加一個最終else子句您若大/ elif的語句：

else: 
    print "Did not find answer" 
    print repr(player_choice), repr(computer_choice) 

如果不打的話，就意味着你有一個錯字別的地方，也許吧。無論如何，如果需要的話，你當然可以添加更多的調試語句 - 每個elif子句一個。

這引出了另一點 - 你有很多if/elif子句。

您可能想要調查一些可以添加在一起的值或可以調用的函數的字符串，以減少所需的if/else語句的數量。
