我能够去通过第一个功能....但第二FUNC没有运行....的getActionpython-执行时间问题

这是我的功能:当我执行,它让我感到节点的价值,但不是它,它给了我错误。 get操作函数中的i = 0的值。我不知道,为什么它不增加。
while stack.isEmpty()!= 0:
node = stack.pop()
print node
错误:
(5, 5)
Path found with total cost of 999999 in 0.0 seconds
Search nodes expanded: 1
None
这不是一个错误,这只是正常的输出。 – Zaz 2010-08-03 10:47:30
