错误提示:Traceback (most recent call last):

相关函数不是定义了吗,怎么还会这样,求解,谢谢
代码如下
from random import choice

print_caves()
link_caves()
print_caves()
finish_caves()

player_location=choice(cave_numbers)

player_location=choice(cave_numbers)
while True:
print_location(player_location)
new_location=get_next_location()
if new_location is not None:
player_location=new_location
if player_location==wumpus_location:
print"你被怪物吃掉了"
break

这段代码问题太多了。不妨从这里开始：
不要一次编写超过20行代码，老代码能运行了，再加新代码
使用pylint等工具检查代码
避免使用全局变量
NameError: name 'visit_cave' is not defined
这个错误是因为在第7行调用这个函数的时候，这个函数还没有定义。方法是把代码按下面的顺序重新排序：
import语句
变量定义和初始化
函数定义
具体语句（模块初始化）
