Python全局名称'；选择3'；没有定义

我正在尝试为一个类制作一个基于代码的冒险游戏，并不断收到一条错误消息，说“全局名称‘choice3’未定义”。我对编码非常陌生，所以我的代码可能有很多错误，我只是不确定问题出在哪里

            if choice1 == 1:
                print 'After talking to a few guys, you assemble a trustworthy team. Word gets around, and someone wants to join the plan that everyone seems to trust, but you don’t know him very well.'

如果您的代码中有那么多全局变量，您可能需要重新考虑您的设计，您还应该发现

elif

和

，而
loops您从未为choice3分配过任何内容……您在
If
块中分配
choice3
，但稍后调用
choice3
的值。如果代码从未进入该块，则该代码将没有指定值。它将具有值的唯一方法是如果
choice2==1
@Tgsmith61591我不需要代码具有值，除非'choice2==1'。即使当'choice2==1'时，它仍然会给我一条错误消息，表明choice3未定义。
