检查模块可能会有所帮助，特别是getclasstree（）函数：
将给定的类列表排列为嵌套列表的层次结构。在出现嵌套列表的地方，它包含派生自该类的类，这些类的条目紧接在列表之前。
inspect.getclasstree(inspect.getmro(Exception))
或者，您可以递归遍历
__subclasses__()继承树，如下所示：
def classtree(cls, indent=0): print '.' * indent, cls.__name__ for subcls in cls.__subclasses__(): classtree(subcls, indent + 3)classtree(baseException)
印刷品：
baseException... Exception...... StandardError......... TypeError......... importError............ ZipimportError......... EnvironmentError............ IOError............... ItimerError............ OSError......... EOFError......... RuntimeError............ NotImplementedError......... NameError............ UnboundLocalError......... AttributeError......... SyntaxError............ IndentationError............... TabError......... LookupError............ IndexError............ KeyError............ CodecRegistryError......... ValueError............ UnipreError............... UnipreEnpreError............... UnipreDepreError............... UnipreTranslateError......... AssertionError......... ArithmeticError............ FloatingPointError............ OverflowError............ ZeroDivisionError......... SystemError............ CodecRegistryError......... ReferenceError......... MemoryError......... BufferError...... StopIteration...... Warning......... UserWarning......... DeprecationWarning......... PendingDeprecationWarning......... SyntaxWarning......... RuntimeWarning......... FutureWarning......... importWarning.........
