How to catch multiple exceptions in one line (except block)?
To catch multiple exceptions in one except block, you can use the following syntax:
except (SomeException, DifferentException) as e:
pass # handle the exception or pass
If you are using Python 2, you can use the following syntax as the previous one won’t work:
except (SomeException, DifferentException), e:
pass # handle the exception or pass
The last method will still work in Python 2.7 but it is now deprecated in python 3, therefore the first method is recommended.
