I found a workaround by disabling auto-indent when the cursor is in python src-block:

    (defvar et/evil-open-line-no-indent-langs '("python" "ipython"))

    (defun evil-open-no-autoindent (oldfun arg)
      (if (and evil-auto-indent
               (eq major-mode 'org-mode)
               (member (org-eldoc-get-src-lang) et/evil-open-line-no-indent-langs))
          (let ((evil-auto-indent nil))
            (funcall oldfun arg))
        (funcall oldfun arg)))
