>>> ping3.ping("example.com", ttl=1)
[... Traceback ...]
ping3.errors.TimeToLiveExpired: Time exceeded: Time To Live expired.

>>> help(ping3.errors)  # More info about exceptions.

ping3.EXCEPTIONS = True

try:
    ping3.ping("not.exist.com")
except ping3.errors.HostUnknown:  # Specific error is catched.
    print("Host unknown error raised.")
except ping3.errors.PingError:  # All ping3 errors are subclasses of `PingError`.
