python - Python石头，纸，剪刀

Question

我试图学习python并以此开始，当我尝试运行它时，我一直收到语法错误。光标跳到def start部分的close结束处。我不确定语法错误来自哪里，因为我用语音标记了所有打印件

Answer 1

1)您在这里有缩进错误:

try:
            player = int(player)
            if player in (1,2,3):
                return player
except ValueError: #Try Except Block Statement
            pass
            Print "Oops! I didn't understand that. Please enter 1, 2 or 3."

2)另外:

if rules[player} == computer: #Error in this line

应该 :

if rules[player] == computer:

3)缩进错误。

if player == computer:
    print "Tie Game."
else:
    if rules[player} == computer:
    print "Your victory has been assured."
    player_score +=1
else: #Incorrect indentation
    print "The computer laughs as you realise you have been defeated."

应该是:

    if rules[player} == computer:
        print "Your victory has been assured."
        player_score +=1
    else:
        print "The computer laughs as you realise you have been defeated."
