With Org's master (f17d301e1), the second one hangs for me with Emacs 26.3. Quickly stepping through org-babel-python--send-string, it appears to get stuck in the accept-process-output call. Using an Emacs built from master, there's no hang on my end either. If you'd find it useful, I can try to bisect that to a specific Emacs commit tomorrow. The Emacs 26.3 hang goes away after installing your patch that restores the use of a marker.
