Catch multiple exceptions in one line (except block)

manpreet Best Answer 2 years ago

try:
    # do something that may fail
except:
    # do this if ANYTHING goes wrong

try:
    # do something that may fail
except IDontLikeYouException:
    # say please
except YouAreTooShortException:
    # stand on a ladder

try:
    # do something that may fail
except IDontLikeYouException:
    # say please
except YouAreBeingMeanException:
    # say please

try:
    # do something that may fail
except IDontLikeYouException, YouAreBeingMeanException:
    # say please

try:
    # do something that may fail
except Exception, e:
    # say please

From Python Documentation:

An except clause may name multiple exceptions">exceptions as a parenthesized tuple, for example

except (IDontLikeYouException, YouAreBeingMeanException) as e:

    pass

Or, for Python 2 only:

except (IDontLikeYouException, YouAreBeingMeanException), e:

    pass

Separating the exception from the variable with a comma will still work in Python 2.6 and 2.7, but is now deprecated and does not work in Python 3; now you should be using as
