Project Structure

├── app.py
├── templates/
│ ├── index.html

└── README.md

• app.py: Contains the Flask application logic and route definitions.
• templates/: Directory containing the HTML templates for the web pages.
  • index.html: The home page template.
  • about.html: The about page template.
• README.md: This file, providing information about the application.

Prerequisites

Before running the application, ensure you have the following installed:

• Python: (3.6 or higher recommended)
• Flask: (Install using pip)

Installation

1. Clone the repository (if applicable):

   git clone https://github.com/MrTG-CodeBot/python-web
   cd python-web

2. Install Flask:

   pip install flask

How to Run the Application

1. Navigate to the project directory:

   cd python-web

2. Run the Flask application:

   python app.py

   This will start the Flask development server. You should see output similar to this:

   * Serving Flask app "app" (lazy loading)
   * Environment: production
     WARNING: This is a development server. Do not use it in a production deployment.
     Use a production WSGI server instead.
   * Debug mode: on
   * Running on [http://127.0.0.1:5000/](https://www.google.com/search?q=http://127.0.0.1:5000/) (Press CTRL+C to quit)
   * Restarting with stat
   * Debugger is active!
   * Debugger PIN: 123-456-789
   

3. Open your web browser and access the application:

   • Home page: http://127.0.0.1:5000/home
   • About page: http://127.0.0.1:5000/about

4. To stop the server, press Ctrl+C in the terminal.

How to Use the Application

• Home Page:

  •  Displays a welcome message.
    

  •  Provides a link to the "About" page.
    

• About Page:

  •  Displays information about the application, including the user name and server.
    

  • Provides a link back to the "Home" page.

Key Concepts

• Flask: A lightweight and flexible Python web framework.
• Routes: Define the URLs that the application responds to.
• Templates: HTML files used to render the web pages.
• render_template(): Flask function used to render HTML templates.
• Template variables: using the {{ variable_name }} syntax to pass data from python to html.
• Debug Mode: Enables automatic reloading of the server and debugging information.

Notes

• The debug=True option in app.run() enables debug mode. This should be disabled in a production environment.
• For production deployments, use a production-ready WSGI server like Gunicorn or uWSGI.
• Ensure that the templates folder is in the same directory as app.py.
• If you modify the python code, or the html files, the server will reload automatically due to debug mode being on.
