Handle Errors & Execute Try Again in Python

Question

I'm trying to process through my try loop again after an error has been found and handled by except (AttributeError). Right now, the script ends after an error is handled rather than starting from the try loop. Any help getting back to the try loop after an error is encountered would be greatly appreciated.

try:
    #code
except (AttributeError) as error:
    print (error)

What you have is a `try...except`. Nothing is looping, it tries what is in the `try` block and excepts the exceptions you specify. — That1Guy, Jul 14 '15 at 22:00
@That1Guy Is there any way to iterate over the `try` block again after an error is excepted? — pHorseSpec, Jul 14 '15 at 22:02
@NightShadeQueen good idea, I'm just trying to think of a conditional that would end the `while` loop when it's done processing many files in a directory — pHorseSpec, Jul 14 '15 at 22:09

You could create a while loop that encompasses everything:

while True:
    try:
        #code
        break
    except (AttributeError) as error:
        print (error)

I added a break at the end of the try statement because I am under the assumption that once all the try code successfully runs you would like that section to complete.

while True:
    try:
        #code
    except AttributeError as error:
        print(error)
    else:
        break

Control goes to the else block only if there is no exception in the try block. Check this: https://docs.python.org/2/tutorial/errors.html#handling-exceptions

You can do something like this:

retry = False
try:
    #code
except AttributeError as error:
    print error
    retry = True
finally:
    if retry:
        #code
