打印Python异常错误层次结构

打印Python异常/错误层次结构

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：
