Python: catch Exception or keyboard interrupt

Question

I have the following code:

import time

try:
    time.sleep(3)
    raise Exception('error')
except Exception or KeyboardInterrupt:
    print(">>> Error or keyboard interrupt")

I want to catch either error or key board interrupt. But currently, it catches only Exception, keyboard interrupt is not handled.

If I remove Exception and leave only Keyboard interrupt, it catches only keyboard interrupt.
If I remove KeyboardInterrupt and leave only Exception, it catches only Exception.

Is there a way to catch both ?

You can use tuple of exceptions. except (Exception, KeyboardInterrupt): — user459872

If you want to handle the two cases differently the best way of doing this is to have multiple except blocks:

import time

try:
    time.sleep(3)
    raise Exception('error')

except KeyboardInterrupt:
    print("Keyboard interrupt")

except Exception as e:
    print("Exception encountered:", e)

Mind the order!

According to https://docs.python.org/3/tutorial/errors.html#handling-exceptions you can use

except (RuntimeError, TypeError, NameError):

import time

try:
    time.sleep(3)
    raise Exception('error')
except (Exception, KeyboardInterrupt):
    print(">>> Error or keyboard interrupt")
