Question

I have some code I want to execute if an exception is not thrown.

Currently I’m doing this:

try:
    return type, self.message_handlers[type](self, length - 1)
finally:
    if not any(self.exc_info()):
        self.last_recv_time = time.time()

Can this be improved on? Is this the best way to do it?

The optional else clause is executed if and when control flows off the
end of the try clause.

Currently, control “flows off the end” except in the case of an
exception or the execution of a return, continue, or break statement.

Answer 1

Your code suggests that you don’t want to catch the exception if it occurs, so why not simply

result = type, self.message_handlers[type](self, length - 1)
self.last_recv_time = time.time()
return result

(Am I missing anything?)
