It can be if you like that style. You can define re-usable and callable
source blocks and tangle them to their own file and to other files, too.
For example using the example above you can use both approaches:
#+NAME: init
#+BEGIN_SRC python :tangle board.py :comments no
def init_board(args)
return [[-1 for x in range(3)] for y in range(3)]
#+END_SRC
#+NAME: org_gcr_2017-11-30_mara_1BB0EB7B-1693-458D-B1AD-CE44ED9961C1
#+BEGIN_SRC python :comments no :tangle program.py
import sys
import os
«init»
def main(args):
init_board(args)
if __name__ == "__main__":
main(sys.argv)
#+END_SRC
Calling `org-babel-expand-src-block'
