以下python代码抛出此错误消息,我不知道为什么,我的选项卡似乎排成一行:

File "test.py", line 12
    pass
       ^ TabError: inconsistent use of tabs and spaces in indentation

我的代码:

class eightPuzzle(StateSpace):
    StateSpace.n = 0

    def __init__(self, action, gval, state, parent = None):
        StateSpace.__init__(self, action, gval, parent)
        self.state = state

    def successors(self) :
        pass
