Potential fix for code scanning alert no. 1: Flask app is run in debug mode

[leandro3810]

Potential fix for https://github.com/leandro3810/python25/security/code-scanning/1

To fix the issue, we should ensure that the Flask application does not run in debug mode in a production environment. The best practice is to use an environment variable to determine whether the application should run in debug mode. This allows the application to run safely in production while still enabling debug mode during development.

We will:

1. Introduce a check for an environment variable (e.g., FLASK_ENV) to determine whether the app should run in debug mode.
2. Default to running the app with debug=False if the environment variable is not set or indicates a production environment.
3. Update the app.run() call to use this logic.

Summary by Sourcery

Prevent the Flask application from running in debug mode in production by toggling debug based on the FLASK_ENV environment variable.

Bug Fixes:

• Disable Flask debug mode by default to address the code scanning alert.

Enhancements:

• Add environment variable check to set debug mode only when FLASK_ENV is 'development'.

Reviewer's Guide

Refactor Flask app startup to conditionally enable debug mode based on the FLASK_ENV environment variable, defaulting to false in production.

Hey @leandro3810 - I've reviewed your changes - here's some feedback:

• Move the import os statement up into the top-of-file import section to keep imports organized.
• Consider relying on Flask's built-in FLASK_DEBUG or app.config['DEBUG'] settings (via flask run) instead of custom logic, to follow standard Flask conventions.
