ロック、ペーパー、はさみのpython

Question

私は、pythonを学習し、岩、紙、はさみのゲームをコーディングしています。私はプログラムを実行することができますが、プログラムがネストされたif、elif、elseステートメントを通過するたびに、出力はhumplayer変数の値に関係なく、外部elseステートメントに続きます。どんな助け？

ありがとうございました！

main() 

Answer 1

あなたがintにキャストされていない、人間からの入力をお願いし-再。むしろ、この行の書き換えより：あなたは適切にあなたがいないあなたのhum_player()機能でintにキャストがドン 「tはあなたが書いた機能を使用して行う、

humplayer = hum_player() 

なぜ

humplayer=input("Enter your move (0 for Rock, 1 for Paper, and 2 for Scissors): ") 

をあなたが再クエリーする他のすべての場所で。この機能を再利用することもできます。それが最初に別々の関数を書く理由です（既に書いたコードを繰り返す必要はありません）。

もう少し間違っているのは、statistics()メソッドを使用している方法です。

def statistics(playerName,humScore,tieScore,comScore): 
    print("There were", tieScore+comScore+humscore, "games:", playerName, "won", humScore, "games, the computer won", comScore, "games and there were", tieScore, "ties.") 

これは実際にはOKです。問題は、実際のstatistics方法はNoneので、このprint文を返し

'print(statistics(...))` 

でそれを呼び出している（実際の関数呼び出しは、まだコンソールに出力しますが）Noneを印刷しようとしていることです。 print文なし

statistics(...) 

、または文字列を返すのではなく、それを印刷するには、あなたしている統計方法を変更：行うには良い方法は、どちらかだけのメソッドを呼び出すことです。

def statistics(playerName,humScore,tieScore,comScore): 
    return ("There were", tieScore+comScore+humscore, "games:", playerName, "won", humScore, "games, the computer won", comScore, "games and there were", tieScore, "ties.")
