python 中的 any 命令行选项是否用于打印异常/错误类层次结构？
输出应该类似于http://docs.python.org/2/library/exceptions.html#exception-hierarchy
最佳答案
inspect模块可能有帮助，特别是 getclasstree()功能:
Arrange the given list of classes into a hierarchy of nested lists. Where a nested list appears, it contains classes derived from the class whose entry immediately precedes the list.
inspect.getclasstree(inspect.getmro(Exception))
或者，您可以通过继承树向下递归遍历 __subclasses__()，如下所示:
def classtree(cls, indent=0):
print '.' * indent, cls.__name__
for subcls in cls.__subclasses__():
classtree(subcls, indent + 3)
classtree(BaseException)
打印:
