Calling e.args means that you can access the attributes of the exception object. But it won't catch BaseException or the system-exiting exceptions SystemExit, KeyboardInterrupt and GeneratorExit

Here is its sample:

try:
    i = 1/0
    print(i)
except Exception as e:
    print (e.args)

This will print:

('division by zero')

More ever If we rasie BaseException error

try:
    raise BaseException()
except Exception as e:
    print (e.args)

The output will be like this

runfile('W:/Summerizer/except.py', wdir='W:/Summerizer')
Traceback (most recent call last):

  File "<ipython-input-3-11e8f07e28c7>", line 1, in <module>

    raise BaseException()

BaseException

Here as is used to access more functions(args,message etc) so you can understand error more efficiently.
