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字游戏，第一部分很好，然后我尝试添加一个商店，当代码运行时，商店只能进入一次。这是代码

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!"

我对 Python 很陌生，大约 2-4 周。所以如果可能的话，请不要复杂的答案：D

我想知道出了什么问题以及如何解决它的想法。谢谢：D PS如果你想提出一个可以添加的想法，你可以这样做！编辑：更改代码，新错误

Traceback (most recent call last):
  File "C:\Users\ImGone\Desktop\MoneySurvival_bakcup.py", line 173, in <module>
    do_farm()
  File "C:\Users\ImGone\Desktop\MoneySurvival_bakcup.py", line 46, in do_farm
    entertainment = entertainment - random.randrange(1,7+1)
UnboundLocalError: local variable 'entertainment' referenced before assignment

您永远不会清除shop_choice，因此下次有人试图去商店时，他们会立即离开（因为从他们上次访问然后离开商店时shop_choice已经设置为）。L

除了 Amber 发现的问题之外，您还遇到了一些压痕问题，这些问题会使您难以到达商店。

shop == "P"支票在箱子rest <= 0里面choice == "F"。所以，去商店的唯一方法就是去农场，用完你所有的休息。这不可能。

如果您将代码分解为函数，这会简单得多，如下所示：

def do_farm():
    entertainment = entertainment - random.randrange(1,7+1)
    # ...

然后你的主循环可以这样做：

if choice == "F":
    do_farm()
elif choice == "S":
    do_shop()
# ...

此外，如果您以相反的方式进行操作，则更容易使循环正确，即要求在循环顶部而不是底部进行选择。例如：

def shop():
    while True:
        shop()
        shop_choice = raw_input("Shop command: ")
        if shop_choice == "I":
            do_shop_inventory()
        elif shop_choice == "R":
            # ...
        elif shop_choice == "L":
            break

while True您必须执行 a和 a而不是将条件直接放入循环中，这有点烦人break，但另一种方法是编写相同的输入代码两次（一次在循环之前，一次在结束时）而不是一次（在循环的顶部），或者编写可以处理“还没有输入”状态的复杂代码。
