Question

我最近开始学习python，并尝试在python 2.7中制作一个简单的游戏，其中计算机随机生成一个1到6之间的数字，而玩家输入一个1到6之间的数字。规则是更大的数字获胜，但除外如果一个人有6个，而另一个人有1个，在这种情况下，拥有1个的人获胜。游戏还应该问第一个问题，如果玩家回答“是”，则游戏将继续。否则它将执行其他过程。但是，当我运行代码时，即使计算机生成的数量更高，也不会向计算机添加任何点。另外，如果我输入no或其他内容，即使我试图获取打印其他代码的代码，代码也会继续启动游戏。

我尝试只使用if else语句而不使用try，除了将开始提示符更改为布尔型语句外。

import random as r

score1 = 0
score2 = 0

start = raw_input("Would you like to start a new game")


if start == "yes" or " yes":
    print "Choose a number between 1 and 6"
    print "Enter stop to end game"
    choice1 = raw_input("Pick a number")
    choice2 = r.randint (1,6)
    while choice1 != "stop":
        try:
            if choice1 > choice2:
                score1 = score1 + 1
                print "The computer picked: " + str(choice2)
                choice1 = raw_input("Pick a number")
                choice2 = r.randint(1, 6)
            elif choice2 > choice1:
                score2 = score2 + 1
                print "The computer picked: " + str(choice2)
                choice1 = raw_input("Pick a number")
                choice2 = r.randint(1, 6)
        except:
            if choice1 == 1 and choice2 == 6:
                score1 = score1 + 1
                print "The computer picked: " + str(choice2)
                choice1 = raw_input("Pick a number")
                choice2 = r.randint(1, 6)
        else:
            if choice1 == 6 and choice2 == 1:
                score2 = score2 + 1
                print "The computer picked: " + str(choice2)
                choice1 = raw_input("Pick a number")
                choice2 = r.randint(1, 6)

    print "Final score is: " + str(score1) + " and Computer is: " + str(score2)
elif start == "no" or " no":
    print "Maybe another time"
else:
    print "Please enter yes or no"
    start = raw_input("Would you like to start a new game")

程序输出：

Would you like to start a new game no
Choose a number between 1 and 6
Enter stop to end game
Pick a number1
The computer picked: 2
Pick a number1
The computer picked: 4
Pick a number1
The computer picked: 5

The computer picked: 3

The computer picked: 2

Final score is: 5 and Computer is: 0

首先，这句话

if start == "yes" or " yes":

被评估为（start =='yes'）或（'yes'）。由于“是”是一个常数，并且始终为true，因此它将始终为true。相反，请尝试这样做，这样会在评估之前在正面或背面留出空间。

if start.strip() == 'yes':

如果有多个条件，我还会考虑您在其他地方的情况。考虑使用parens以确保代码正在按您期望的方式进行评估。例如，

if (choice1 == 1) and (choice2 == 6):

此外，try\expect用于记录异常。我不确定您希望在此处记录哪些异常。最好检查用户输入并确保它是数字，而不是依靠try\expect
