AttributeError:stat实例没有属性X？

Question

运行以下代码时,我得到了AttributeError: stat instance has no attribute 'printStats'.这里有什么问题？

class stat():
    def __init__(self, fname, blocks, backEdges):
        self.fname = fname
        self.blocks = blocks
        self.backEdges = backEdges

    def printStats(self):
        print self.fname + str(self.blocks) + str(self.backEdges)

element = stat("a", 1, 2)
element.printStats()

Answer 1

你的缩进是愚蠢的,混合标签和空格.使用python -tt来验证.
