所以我现在已经尝试了数百次，我尝试使用循环和大量其他东西，但似乎没有任何东西可以按照我的意愿工作。大多数时候，当我定义一个函数时，它只是在第一部分之后变成空白，它可能会走得更远，但我不知道。另外，正如您从这个尴尬的问题中可以看出的那样，我是编程新手，请帮助我，如果有人能解释为什么它只打印到动作函数定义的文本。

您想在定义后调用该函数：

action_function()

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

您还想action_function()从函数的第一行删除调用。

其他一些提示：

  • 不要创建name_x一系列变量。改用列表：

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

  • 如果要将 5 添加到gold变量中，则需要将其存储回该变量中：

    gold = gold + 5

    或者，更短：

    gold += 5

  • 该.index(1)函数查找值的列表索引1；您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。

    如果您使用列表作为鱼和垃圾变量，您可以执行以下操作：

    if inventory[0] in fish:
    sold = inventory.pop(0)
    gold += 5
    print "You have sold a", sold, "for 5 gold coins!"

    并消除所有多余的if分支。

  • 不要使用递归，而是使用循环：

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