我试图学习 python 并从这个开始，当我尝试运行它时，我不断收到语法错误。光标跳到 def start 部分的“关闭”末尾。我不确定语法错误来自哪里，因为我语音标记了所有打印

1）你在这里有一个缩进错误：

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）还有：

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

应该 ：

if rules[player] == computer:

3) if else 中的缩进错误。

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."

这应该是：

    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."

if rules[player} == computer:

花括号应该是一个括号。

if rules[player} == computer:
print "Your victory has been assured."
player_score +=1

第一个错误：rules[player} => rules[player] 第二个错误，你需要识别 if 后面的行。

else:
    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."

第三个错误：一个 if 不能有 2 个 else
