我正在尝试制作一个简单的文字游戏，然后我继续学习更多的东西，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很新，大概2-4周。所以，如果可能的话，请不要复杂的答案：D
我想知道什么是错的，并想知道如何解决它。 感谢：D 附：如果你想提出一个可以添加的想法，你可以这样做！ 编辑： 更改了代码，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
答案 0 :(得分：3)
您永远不会清除shop_choice，所以下次有人试图去商店时，他们会立即离开（因为shop_choice已经设置为L访问然后离开商店）。
答案 1 :(得分：0)
除了Amber发现的问题之外，你还有一些缩进问题会让你难以到达商店。
shop == "P"检查位于rest <= 0案例中的choice == "F"案例内。所以，去商店的唯一方法就是到农场去休息。这不可能是正确的。
如果将代码分解为函数，这会更简单：
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()
# ...
另外，如果你以相反的方式做事情，那么让循环更容易，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
您必须执行while True和break而不是将条件直接放在循环中，这有点令人讨厌，但另一种方法是将相同的输入代码写入两次（之前一次）循环，再次在结束时）而不是一次（在循环的顶部），或者编写可以处理“无输入”状态的复杂代码。
