Two things:

1. Library-of-Babel :: lets you store src blocks of code in an external file

2. noweb chunks :: let you insert code into src blocks

See https://orgmode.org/worg/library-of-babel.html and (info "(org) Noweb Reference Syntax")

For your example, a file `my-lob.org' with a src-block named foo-py that contains what foo.py contains will do it.

Then you eval `(org-babel-lob-ingest "my-lob.org")' any time before executing the file that contains this:

#+begin_src python :noweb yes
<<foo-py>>
...

HTH,
