Good advice, so change to the following:
(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 (expand-file-name python-version))
(car (split-string (buffer-string)))))))))
