所以我现在已经尝试了数百次，我尝试使用循环，还有很多其他的东西，似乎没有什么工作我想要它。大多数时候，在我定义一个函数的第一部分之后它只是空白，它可能已经走得更远，但我无法分辨。另外你可以从这个尴尬的问题中看出我是编程的新手，请帮助我，如果有人可以解释为什么它只打印文本到动作函数的定义。

您想在定义后调用该函数：

action_function()

请记住，Python通过缩进来定义块，因此将action_function()行放在与def action_function():行相同的缩进级别上。

您还想从功能的第一行删除action_function()来电。

其他一些提示：

不要创建name_x系列变量。改为使用列表：

fish = ["Mackarel", "Cod", "Salmon", "Herring", "Tuna"]

如果要在gold变量中添加5，则需要将其存储在该变量中：
```
gold = gold + 5
```
或者更短：
```
gold += 5
```
.index(1)函数查找值1的列表索引;你可能想直接使用索引：
```
if inventory[0] == something:
```
请记住，Python列表索引从 0 开始，而不是1。

如果您对fish和trash变量使用列表，则可以执行以下操作：
```
if inventory[0] in fish:
    sold = inventory.pop(0)
    gold += 5
    print "You have sold a", sold, "for 5 gold coins!"
```
并消除所有额外的if分支。

使用循环代替使用递归：

while True:
    # print, get input, do actions
    # when done, use `break` to stop the loop.
