Python新手练习: Rock Paper Scissors

Question

我一直在尝试编写一个简单的 RPS 游戏，用户可以在其中与计算机对战。此时只有 1 次迭代(因为我卡住了......)并且没有验证用户输入是否有效。我遇到的问题是，无论我尝试做什么以将计算机和用户的分数存储在一个变量中，它们始终等于 0，无论我尝试了何种缩进或我尝试将返回放在何处. (正如您在下面的代码中看到的那样……我尝试过但没有成功的一些部分被注释掉了)。理想情况下，由于我计划多次迭代，我希望更新变量 u 和 v 本身并保持得分，而不仅仅是打印谁赢得了特定迭代。

你能帮我理解我做错了什么吗？

from random import randrange
rps = ["r", "p", "s"]



def gameplay(user,comp):
    u = 0 #user's score
    v = 0 #computer's score
    print "Computer chose: " + comp
    if comp == user:
        pass
    elif comp == "r" and user == "p":
        u += 1
        #print u
        #return u

    elif comp == "r" and user == "s":
        v += 1
        #print v
        #return v

    elif comp == "p" and user == "s":
        u += 1
        #print u
        #return u

    elif comp == "p" and user == "r":
        v += 1
        #print v
        #return v

    elif comp == "s" and user == "r":
        u += 1
        #print u
        #return u

    elif comp == "s" and user == "p":
        v += 1
        #print v
        #return v

    return u
    return v

gameplay(raw_input("your move?"),rps[randrange(3)])
print u
print v

只是为了好玩......看看你是否能理解这个OOP实现(开始学习OOP永远不会太早)

WIN,TIE,LOSE = 1,0,-1
class RockPaperScissors:
    def __str__(self):
        return self.__class__.__name__
class Rock(RockPaperScissors):
    def __cmp__(self,other):
        if isinstance(other,Rock): return TIE
        if isinstance(other,Paper): return LOSE
        return WIN

class Paper(RockPaperScissors):
    def __cmp__(self,other):
        if isinstance(other,Paper): return TIE
        if isinstance(other,Scissors):return LOSE
        return WIN

class Scissors(RockPaperScissors):
    def __cmp__(self,other):
        if isinstance(other,Scissors): return TIE
        if isinstance(other,Rock):return LOSE
        return WIN

def RPS(ltr_code):
    return {'r':Rock,'p':Paper,'s':Scissors}[ltr_code.lower()]()


player = RPS("r")
computer = RPS("s")
if player > computer:
    print "Player Wins! %s beats %s"%(player,computer)
elif player < computer:
    print "Computer wins!! %s beats %s"%(computer,player)
else: 
    print "Tied!! %s ties %s"%(computer,player)
