怎么raise A, B办？它和它有什么不同raise A？

一些例子(在python 2.7的解释器上运行):

class E(Exception):
    pass
e = E()

raise Exception, e
Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
__main__.E

raise Exception(e)
Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
Exception

raise (Exception, e)
Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
Exception

谢谢!
