Flask: Making my first web site

[snippsat]

Change config.py to:

import os

class Config:
    SECRET_KEY = '12345'
    SQLALCHEMY_DATABASE_URI = 'sqlite:///site.db'
    MAIL_SERVER = 'smtp.googlemail.com'
    MAIL_PORT = 587
    MAIL_USE_TLS = True
    MAIL_USERNAME = 'Test'
    MAIL_PASSWORD = '99999'

What happens when use os.environ.get is that Corey is taking environment variables from his own OS.
This will not be the same for you.

If want look at your environment variables.

>>> import os
>>> 
>>> os.environ

This is done for safety concern for not having these values directly in code,but getting them from OS.
I like better python-dotenv for having environment variable closer to project and not on OS.

You don't have to think of these safety yet,as running the local development server now.
