What I do for cases like this, where I do not want the input to some src block exported, is put the input (the example block in your case) in a drawer and set the option d:nil so as to not export drawers.
5 1 3 2 0
You could put the example in a separate section and tag it noexport:
* example input :noexport:
5 1 3 2 0
* example code
#+begin_src python :results output :eval yes :var x=input :exports results
import matplotlib.pyplot as plt
import numpy as np
x = ...
Not that I know of, but Org mode provides the ingredients to roll your own easily:
(defun org-table-goto-beginning ()
(defun org-table-goto-end ()
(define-key org-mode-map (kbd "C-c t b") #'org-table-goto-beginning)
(define-key org-mode-map (kbd &...
C-c C-v C-t runs org-babel-tangle and exports all code blocks to the current buffer name plus the correct code extension (e.g. html blocks get .html, python blocks get .py). You can specify the tangled filename with the :tangle property at the header, section, or file level.
Run C-u C-c C-v C-t to only tangle the current code block containing the point.
I don't think org offers any way to exclude example blocks from exporting. A possible work-around: if you don't want the example to show up in your export, does it need to be an example? You could make it a bash code block instead:
#+begin_src bash :exports none
echo 5 1 3 2 0
#+begin_src python :results output :eval yes :...
There are so many options. You can define a function to insert a string, or use the built-in skeleton library like this:
"A meeting skeleton" nil
then to insert your template, type M-x meeting-skeleton at the place you want to insert the string.
Another option is yas-...
You should be able to use directory-local variables for this: do C-h i g(emacs)Per-directory local variables RET to find out more information.
Briefly, create a file named .dir-locals.el in your blog directory where the Org mode files that you publish are kept. Put the following in the file:
((org-mode . ((org-html-head-include-default-style . nil)
