Thank you for your comment and help. In order to be more in line with
the actual situation, I replaced the variable name `venvdir'  with
`project-dir':

  (defun try/pyvenv-workon ()
    (when (buffer-file-name)
      (let* ((python-version ".python-version")
             (project-dir (locate-dominating-file (buffer-file-name)
python-version)))
        (when project-dir
          (pyvenv-workon
            (with-temp-buffer
              (insert-file-contents (format "%s%s" project-dir python-version))
              (car (split-string (buffer-string)))))))))
