Answer 1

If you are the one coding the fucntions, why not program the functions to return status codes? Then they will be atomic and you wont have to capture the error in the main section. You will also be able to perform roll back or alternate coding on failure.

def do_magic():
    try:
        #do something here
        return 1
    except:
        return 0

in main program..

if do_magic() = 0:
   #do something useful or not...

if do_foo() = 0:
   #do something useful or not...

if do_bar() = 0:
   #do something useful or not...
