You just use the dependencies, for example:

  $ cat /tmp/hello.py 
  #! /opt/appfs/rkeene.org/python3/platform/latest/bin/python3
  print("Hello, world!".rjust(20, "-"))

  $ /tmp/hello.py     
  -------Hello, world!

The really nice thing about the nix-shell example is I can specify external python dependencies within the script itself, and even the python version itself, all within one file, and nix-shell just takes care of it.

If you change `latest` to the version [0], then you'll get that exact version.

Additionally any external dependencies can be specified by just accessing them the same way you would in `nix-shell`, just using the path instead of installing. For example, if you wanted to use the "awscli" (the only Python package I already created within AppFS) you would do:

  $ cat /tmp/aws.py 
  #! /opt/appfs/rkeene.org/python3/platform/latest/bin/python3
  import sys
  sys.path.append('/opt/appfs/rkeene.org/aws-cli/platform/latest/lib/python3.6/site-packages')
  import awscli
  
  print(awscli)

  $ /tmp/aws.py     
  <module 'awscli' from '/opt/appfs/rkeene.org/aws-cli/platform/latest/lib/python3.6/site-packages/awscli/__init__.py'>
