[Python] How can a Python enum accept any value without raising ValueError

Suppose I am implementing a network service that receives commands. I want to have an enumeration of these commands, so I can write something like:

class Command(enum.Enum):
ECHO = 0x01
LOGIN = 0x02
SEND_FILE = 0x03

def handle_packet(p: bytes):
command = Command(p[0])
if command == Command.ECHO:
print(p[1:])
elif ...
elif ...
else:
print('Ignoring unknown command', command)


If the client supports a newer version of this protocol than my server, they might send a command that I don't have listed in my enum. For example, if the client sends me 0x04, the constructor Command(p[0]) will throw a ValueError.

Instead, I'd like command = Command(0x04) to create an instance where command.value = 4 and it has a name generated on-the-fly like COMMAND_04.
