At least for unnamed session it's set to nil here

let* ((session (org-babel-python-initiate-session...

later on it takes the wrong route:

(defun org-babel-python-evaluate
   (session body &optional result-type result-params preamble)
   "Evaluate BODY as Python code."
   (if session
       (org-babel-python-evaluate-session
        session body result-type result-params)
     (org-babel-python-evaluate-external-process
      body result-type result-params preamble)))

Best,
