Deleting session variable while avoiding KeyError exception

One of the ways to delete a Django session variable is:

del request.session["sess_variable"]

This naturally gives a KeyError exception in case sess_variable wasn't in the request.session dictionary.

To handle this exception, one can wrap the line in try, except KeyError. But is there a separate command one can use that doesn't throw an error if the key doesn't exist?

You can pop the key from the session. If you specify None as the default, then you won't get a KeyError.

request.session.pop("sess_variable", None)
