📎 Exceptions as Control Flow

Python except construct allows to manage how the application behaves depending on which exception has been raised. documented stimulates to add fields and properties to your exception classes, which you can neatly use in except clauses:

try:
    hal.do_stuff()
except HALHasGoneCrazy as err:
    if err.is_moebius_cycle:
        hal.turn_off()
    else:
        hal.self_check()
