I know using below code to ignore a certain exception, but how to let the code go back to where it got exception and keep executing? Say if the exception \'Exception\' raises in

    update. The way to ignore specific exceptions is to catch the type of exception that you want, test it to see if you want to ignore it and re-raise it if you dont.

    try:
        do_something1
    except TheExceptionTypeThatICanHandleError, e:
        if e.strerror != 10001:
            raise
    finally:
         clean_up
    

    Note also, that each try statement needs its own finally clause if you want it to have one. It wont 'attach itself' to the previous try statement. A raise statement with nothing else is the correct way to re-raise the last exception. Don't let anybody tell you otherwise.


    What you want are continuations which python doesn't natively provide. Beyond that, the answer to your question depends on exactly what you want to do. If you want do_something1 to continue regardless of exceptions, then it would have to catch the exceptions and ignore them itself.

    if you just want do_something2 to happen regardless of if do_something1 completes, you need a separate try statement for each one.

    try:
       do_something1()
    except:
       pass
    
    try:
       do_something2()
    except:
       pass
    

    etc. If you can provide a more detailed example of what it is that you want to do, then there is a good chance that myself or someone smarter than myself can either help you or (more likely) talk you out of it and suggest a more reasonable alternative.
