Python, using variables from __init__ in a parent dir
Question: I have a website I've been writing using Flask, although for this question I
do not think that's relevant. This is the folder structure I'm working with.
Rhea is the name of the project and the parent directory.

    
    
    Rhea
    |- Scripts
        |-script1.py
    |- Static
    |- Templates
    |- __init__
    

My problem is I declare variables inside my init that I need to use inside
script1.py. How do I import these into script1.py?

For reference this is my init file

    
    
    import os
    from flask import Flask
    from flask_appconfig import AppConfig
    from flask_bootstrap import Bootstrap
    from flask.ext.sqlachemy import SQLAlchemy
    
    from .frontend import frontend
    from .nav import nav
    from .models import User
    
    basedir = os.path.abspath(os.path.dirname(__file__))
    
    SQLALCHEMY_DATABASE_URI = 'sqlite:///' + os.path.join(basedir, 'db', 'userdb.db')
    SQLALCHEMY_MIGRATE_REPO = os.path.join(basedir, 'db')
    WTF_CSRF_ENABLED = True
    BOOTSTRAP_SERVE_LOCAL = True
    SECRET_KEY = --SNIP--
    
    app = Flask(__name__)
    app.config.from_object(__name__)
    
    AppConfig(app)
    Bootstrap(app)
    db = SQLAlchemy(app)
    app.register_blueprint(frontend)
    nav.init_app(app)
    
    app.run(host='0.0.0.0', port=6060, debug=False);
    
    return app
    

The variables I need is db, SQLALCHEMY_DATABASE_URI, and the
SQLALCHEMY_MIGRATE_REPO.

Thank's for any help.


Answer: _A_ solution is to append the the `sys.path` with the `Rhea`'s package parent
directory. But it's ugly.

    
    
    # cript1.py 
    import os
    import sys
    
    rhea_dir = os.path.dirname(os.path.dirname(os.path.dirname(__file__)))
    sys.path.append(rhea_dir)
    
    import Rhea
    print Rhea.SQLALCHEMY_DATABASE_URI
