Short (and pretty darned accurate) answer: no.
You can run any shell COMMAND (including shell scripts) from within a
python program via system or popen, or whatever.  You won't easily be
able to call a function from within a shell script, though.

You could make "script wrappers" for all of those functions.  If you
have a master shell script that acts like a library, defining several
functions, but executing none of them, then you could make several
wrappers, each of them a script... like so:

#!/bin/sh
source master.sh
# function foo is defined in master.sh
foo $@

Then, you can call this file (foo.sh) via system from within python.

Shell scripts usually have .sh extensions, but on unix, the extension
exists only for the user's convenience.  It usually has no relevance
for the os.
