exception - How to write multiple try statements in one block in python?

Question

I want to do:

try:
    do()
except:
    do2()
except:
    do3()
except:
    do4()

If do() fails, execute do2(), if do2() fails too, exceute do3() and so on.

best Regards

If you really don't care about the exceptions, you could loop over cases until you succeed:

for fn in (do, do2, do3, do4):
    try:
        fn()
        break
    except:
        continue

This at least avoids having to indent once for every case. If the different functions need different arguments you can use functools.partial to 'prime' them before the loop.
