I fixed it by downgrading to an older release again. #+BEGIN_SRC python even = [] for i in range(10): if i % 2 == 0: even.append(i) else: print("here") even.append(("this should be in the list as well",)) even #+END_SRC Emacs : GNU Emacs 25.2.2 (x86_64-pc-linux-gnu, GTK+ Version 3.22.21) of 2017-09-22, modified by Debian Package: Org mode version 9.1.14 (9.1.14-1-g4931fc-elpa @ /home/paul/org-mode/lisp/) current state: ============== (setq org-src-lang-modes '(("jupyter-python" . python) ("latex-macros" . latex) ("ipython" . python) ("ocaml" . tuareg) ("elisp" . emacs-lisp) ("ditaa" . artist) ("asymptote" . asy) ("dot" . fundamental) ("sqlite" . sql) ("calc" . fundamental) ("C" . c) ("cpp" . c++) ("C++" . c++) ("screen" . shell-script) ("shell" . sh) ("bash" . sh)) org-journal-mode-hook '(#[nil "\301\302\303\304$\207" [org-journal-encrypt-on org-add-hook org-journal-encryption-hook nil t] 5] (lambda nil (org-add-hook org-journal-encrypt-on (quote org-journal-encryption-hook) nil t) ) ) org-tab-first-hook '(org-babel-hide-result-toggle-maybe org-babel-header-arg-expand) org-speed-command-hook '(org-speed-command-activate org-babel-speed-command-activate) org-ellipsis "⤵" org-occur-hook '(org-first-headline-recenter) org-metaup-hook '(org-babel-load-in-session-maybe) org-confirm-shell-link-function 'yes-or-no-p org-time-stamp-custom-formats '("<%a %d %B>" .
