python - How to determine if an exception was raised once you're in the finally block?

Question

Is it possible to tell if there was an exception once you're in the finally clause? Something like:

try:
    funky code
finally:
    if ???:
        print('the funky code raised')

I'm looking to make something like this more DRY:

try:
    funky code
except HandleThis:
    # handle it
    raised = True
except DontHandleThis:
    raised = True
    raise
else:
    raised = False
finally:
    logger.info('funky code raised %s', raised)

I don't like that it requires to catch an exception, which you don't intend to handle, just to set a flag.

Since some comments are asking for less "M" in the MCVE, here is some more background on the use-case. The actual problem is about escalation of logging levels.

• The funky code is third party and can't be changed.
• The failure exception and stack trace does not contain any useful diagnostic information, so using logger.exception in an except block is not helpful here.
• If the funky code raised then some information which I need to see has already been logged, at level DEBUG. We do not and can not handle the error, but want to escalate the DEBUG logging because the information needed is in there.
• The funky code does not raise, most of the time. I don't want to escalate logging levels for the general case, because it is too verbose.

Hence, the code runs under a log capture context (which sets up custom handlers to intercept log records) and some debug info gets re-logged retrospectively:

try:
    with LogCapture() as log:
        funky_code()  # <-- third party badness
finally:
    # log events are buffered in memory. if there was an exception,
    # emit everything that was captured at a WARNING level
    for record in log.captured:
        if <there was an exception>:
            log_fn = mylogger.warning
        else:
            log_fn = getattr(mylogger, record.levelname.lower())
        log_fn(record.msg, record.args)

Answer 1

raised = True
try:
    funky code
    raised = False
except HandleThis:
    # handle it
finally:
    logger.info('funky code raised %s', raised)

Given the additional background information added to the question about selecting a log level, this seems very easily adapted to the intended use-case:

mylog = WARNING
try:
    funky code
    mylog = DEBUG
except HandleThis:
    # handle it
finally:
    mylog(...)
