Can exceptions be caught from both a try and except block with one except statement?

Question

In Python, can an exception be caught from an exception, and from the original try, with the same except statement?

For example, in the following code:

try:
    risky_operation() # This could raise a or b, or it could work
except a:
    simple_operation() # This could raise b, or it could work
except b:
    guaranteed_operation() # This will always work

Would guaranteed_operation() be called if risky_operation() raised b? Or would I have to do:

try:
    risky_operation() # This could raise a or b, or it could work
except a:
    try:
        simple_operation() # This could raise b, or it could work
    except b:
        guaranteed_operation() # This will always work
except b:
    guaranteed_operation() # This will always work
