I tried for a second or so to make this a bit more declarative like but I guess it's not worth it until we have a lot more of these patterns:

@dataclass
class placeholder:
  name: str
  def to_glob(self): return '*'
  def to_re(self): return r'(?P<{self.name}>[^:]+)'

@dataclass
class query:
  items : list
  def to_glob(self): return ':'.join(i.to_glob() for i in self.items if not isinstance(i, str) else i)
  def to_re(self): return re.compile(':'.join(i.to_re() for i in self.items if not isinstance(i, str) else i))

q = query(['lock', 'celery', 'user', placeholder('user_id'), 'task', palceholder('task_name')])

redis_client.keys(q.to_glob())

...

user_id, task_name = q.to_re().match(key).group('user_id', 'task_name')

...
