Question

I am a newbie to python and I have an indentation error message when I commented (‘#’) the two last lines of the following code :

    try:
        return get_callable(callback), {}
#   except (ImportError, AttributeError), e:
#       raise ViewDoesNotExist("Tried %s. Error was: %s" % (callback, st    r(e)))

Can anybody help ?

Answer 1

When commenting out a try / except, place a if True: # in front of the try:

    if True: #try:
        return get_callable(callback), {}
#   except (ImportError, AttributeError), e:
#       raise ViewDoesNotExist("Tried %s. Error was: %s" % (callback, st    r(e)))

This makes for correct syntax without having to de-dent the inner block. You could also add a finally: pass block after the commented except:

    try:
        return get_callable(callback), {}
#   except (ImportError, AttributeError), e:
#       raise ViewDoesNotExist("Tried %s. Error was: %s" % (callback, st    r(e)))
    finally:
        pass

Your only other option is to comment out the try: line as well, and remove the indentation of the block:

#   try:
    return get_callable(callback), {}
#   except (ImportError, AttributeError), e:
#       raise ViewDoesNotExist("Tried %s. Error was: %s" % (callback, st    r(e)))

You cannot leave a bare try: in place without an except or finally block to complete it.
