如何在石頭剪刀布游戲中記分？

Question

我剛剛開始 Python 並編寫一個簡單的石頭剪刀布游戲。 這是我到目前為止所擁有的。 我可以完美地和另一個玩家一起玩游戲。 我想知道的是如何保持勝利的得分，所以如果玩家 1 贏得了第一場比賽，它會說：

玩家 1 = 1 玩家 2 = 0

等等。 此外，如果有任何提示可以使我的代碼更高效（有一個很好的解釋），那就太好了。

謝謝！

Answer 1

考慮這個用於建議的偽代碼（某些部分需要實現）：

# a Player class. it should have a Name and a Score
class Player():
   def __init__(name):
      self.name = name
      self.score = 0

# displays a prompt and reads in the players name returning a string
def getPlayerName():
   # needs code here, see next function for idea of what
   pass

# ask the player to make a choice, takes a Player object
# and returns a string
def getPlayerAttack(player):
    print "%s, what do you choose?" % player.name
    return raw_input("> ")

# determines who wins and updates score accordingly
# takes in the player objects and their attack choices
def attack(player1, choice1, player2, choice2): 
    if choice1 == choice2:
       print "Its's a tie."
    elif choice1 == "1" and choice2 == "2":
       print "%s wins." % player2
       player2.score = player2.score + 1
    elif ... # other attacks

# display the scores of the two players
def displayScores(player1, player2):
    print "%s vs %s" % (player1.score, player2.score)

player1 = Player(getPlayerName())
player2 = Player(getPlayerName())
while true:
    choice1 = getPlayerAttack(player1)
    choice2 = getPlayerAttack(player2)
    attack(player1, choice1, player2, choice2)
    displayScores(player1, player2)

這將需要一些工作，而且它不是超級優化的，但它應該是一個開始並且應該顯示更多的概念。 使用 Ctrl-C 停止或添加停止條件（例如，任一玩家輸入“0”）- 免費包含錯誤。 :)

快樂編碼。

Answer 2

好吧，有幾種方法可以提高效率，但是如果您必須一次輸入一個，我不得不問您將如何玩石頭剪刀布：-P

得分可以歸結為：

if choice1 == choice2 :
    print "Its's a tie."
elif choice1 - choice2 == 1 or choice2 - choice1 == 2 :
    print "%s wins." % player1
else:
    print "%s wins." % player2

如果你想做多個游戲，只需將整個內容放在一個while(1):循環中，並為每個分數添加一個變量。 然后它會變成：

score1 = 0
score2 = 0
while(1):
    <lines 6-18>

    if choice1 == choice2 :
        print "Its's a tie."
    elif choice1 - choice2 == 1 or choice2 - choice1 == 2 :
        print "%s wins." % player1
        score1 = score1 + 1
    else:
        print "%s wins." % player2
        score2 = score2 + 1

    print "%s: %d points. %s: %d points." % (player1, score1, player2, score2)

Answer 3

嘗試這個：

player1 = raw_input("Player 1 name: ")
player2 = raw_input("Player 2 name: ")
while(1)
    player1score = 0
    player2score = 0

    print "%s, what do you choose?" % player1
    print "1. Rock"
    print "2. Paper"
    print "3. Scissors"

    choice1 = raw_input("> ")

    print "%s, what do you choose?" % player2
    print "1. Rock"
    print "2. Paper"
    print "3. Scissors"

    choice2 = raw_input("> ")

    if choice1 == "1" and choice2 == "1":
        print "Its's a tie."

    if choice1 == "1" and choice2 == "2":
        print "%s wins." % player2
        player2score=player2score+1

    if choice1 == "2" and choice2 == "1":
        print "Player 1 wins." % player1
        player1score=player1score+1

    if choice1 == "1" and choice2 == "3":
        print "Player 1 wins." % player1
        player1score=player1score+1

    if choice1 == "3" and choice2 == "1":
        print "%s2 wins." % player2
        player2score=player2score+1

    if choice1 == "2" and choice2 == "3":
        print "%s wins." % player2
        player2score=player2score+1

    if choice1 == "3" and choice2 == "2":
        print "Player 1 wins." % player1
        player1score=player1score+1

    print "Player1: %s" % player1score 
    print "Player2: %s" % player2score
