Python游戏不起作用（商店只出现一次）

在我继续学习更多东西之前，我正在尝试制作一个简单的文本游戏，第一部分很好，然后我尝试添加一个商店，当代码运行时，商店只能输入一次。这是密码

money = 100
entertainment = 30
rest = 15
social = 30
inv = 1
food = 30
score = 1

def commands():
    print "Commands:"
    print " 'P' Print commands options"
    print " 'S' Go to the shop"
    print "Job list? "
    print " 'M' Market"
    print " 'F' Farm"
    print " 'H' Stay at home a rest"
    print " 'E' Entertainment/go to fair"
def shop():
    print "Shop:"
    print " This is the shop, you buy things with your money that you gain"
    print "Press 'I' for a potato! This gives you 20 extra Inventory points! Costs 80 money!"
    print "Press 'R' for a better bed! This gives you 20 extra rest points! Costs 80 money!"
    print "Press 'S' for a texting plan! This gives you 20 extra social points! Costs 80 money!"
    print "Press 'E' for a better tv! This gives you 20 extra entertainment points! Costs 80 money!"
    print "Press 'H' for this list again!"
    print "Press 'L' to return to your game!"

如果钱你从来没有清理过
shop\u-choice
，那么下一次有人试图去商店时，他们会立即离开（因为
shop\u-choice
在他们上次访问然后离开商店时已经设置为
L
。
除了Amber发现的问题，你有一些缩进问题，这会使你很难到达商店

shop==“p”
检查在
rest中，这是一个相当大的控制流。您是否能够隔离导致问题的代码部分？不是您试图解决的问题，而是…第一次，您将
choice
和
shop\u choice
设置为小写
“p”
，这与
choice==“p”
不匹配。（同样，如果用户键入一个小写的
p
它下次将不匹配。）您可能希望所有这些检查都是
choice.upper（）=“p”
之类的，或者更好的是，用
choice=raw\u input（…）
替换
choice=raw\u input（…）。upper（）
。顺便说一句：构建大型交换机（elif语句）像您这样做被认为是一种糟糕的编程实践。至少尝试合并您的条件（您检查不同的条件，但它们都导致相同的打印和退出）在这里，你可以阅读更多：那么我该如何清除它？@ImGone98：问题是你在调用
raw\u input
之前正在检查值，因此它具有你恰好留在那里的任何值。更好的方法是将
raw\u input
移动到循环的顶部。没有代码，这很难解释，所以我把它放在我的位置我要做的是，一开始我没有考虑它，谢谢（：@ImGone98：如果你是指最后一部分……我猜你不想在True
和
break
时做
，而想“一定有更好的方法”…但不幸的是，如果不严格重组代码，没有更好的方法了。我添加了所有这些，但现在它给了我错误？@ImGone98：问题是你试图使用全局变量，但没有声明它们
global
。有时Python可以猜测它们是全局的，但如果不能，你会得到一个
UnboundLocalE错误
。您可以通过将
全局娱乐
添加到函数体顶部来修复此问题。更好的修复方法是重新组织代码，使其不需要全局变量。例如，如果您创建了一个类，所有这些值都作为实例变量，所有这些函数都作为方法，则它们可以执行
自娱乐
，等等。但是在评论中要解释的太多了。
