I used to do this with a dict. Glad this is in Python 3.10.
It will be much more useful as an alternative to dispatch dictionaries, which are more a side-effect of the language lacking any case based control-flow.
Though considered from that perspective, it’s actually a bit of a disadvantage that the new match statement is a part of the language. It’s nice to dynamically extend (either as a first party developer or third party user) that sort of dictionary, effectively adding new branches to the implicit switch statement. A match statement is going to be fixed as written. Probably a readability and consistency win to remove spooky-action-at-a-distance, but at the cost of a bit of (ugly, pragmatic) usability
But if you're not matching structure I really don't see what's wrong with plain old if...elif? And you can easily add more complex tests like "in" clauses this way too:
cmd = args.command
if cmd == 'push':
# do push
elif cmd in ['pull', 'pul']:
# do pull
else:
error(f'command {cmd!r} not yet implemented')
