how to access app.config globally in flask app

In order to access the app.config globally in a Flask app, you can follow the following steps:

  1. Import the Flask module and create an instance of the Flask class:

```python from flask import Flask

app = Flask(name) ```

  1. Create a configuration file for your Flask app. This file should contain the necessary configuration variables. For example, you can create a file named with the following content:

python DEBUG = True SECRET_KEY = 'your_secret_key' DATABASE_URI = 'your_database_uri'

  1. Load the configuration file in your Flask app using the app.config.from_pyfile() method. This will load the configuration variables from the file:

python app.config.from_pyfile('')

  1. You can now access the configuration variables globally within your Flask app. For example, to access the DEBUG variable, you can use app.config['DEBUG']:

python @app.route('/') def home(): debug_value = app.config['DEBUG'] # Rest of your code

Similarly, you can access other configuration variables like SECRET_KEY and DATABASE_URI using app.config['SECRET_KEY'] and app.config['DATABASE_URI'] respectively.

By following these steps, you will be able to access the app.config globally in your Flask app, allowing you to use the configuration variables throughout your code.
