Hi, I was wondering if meltano has a python library or is planning to launch a python library so that all the CLI commands can be incorporated into pythonic functions?

Not currently, but there has been some discussion about it in various threads here and on #C01QS0RV78D calls. https://meltano.slack.com/archives/C01TCRBBJD7/p1662663075779329?thread_ts=1662659343.801819&cid=C01TCRBBJD7
