How to catch multiple exceptions in one line (except block) in Python?


We catch multiple exceptions in one except block as follows

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

try:
raise_certain_errors():
except (CertainError1, CertainError2,…) as e:
handle_error()

Separating the exception from the variable with a comma still works in Python 2.6 and 2.7, but is now deprecated and does not work in Python 3; now we should use ‘as’.

The parentheses are necessary as the commas are used to assign the error objects to names. The ‘as’ keyword is for the assignment. We can use any name for the error object like ‘error’, ‘e’, or ‘err’

Given code can be written as follows

try:
#do something
except (someException, someotherException) as err:
#handle_exception()
