python anywhere just says hello from flask

To create a Flask application that displays "Hello from Flask," you can follow the steps outlined below:

  1. Install Flask:
  2. Flask is a micro web framework for Python. Install Flask by running the command: pip install flask

  3. Import Flask:

  4. In your Python script, import the Flask module by adding the following line of code at the top: from flask import Flask

  5. Create an instance of Flask:

  6. Create an instance of the Flask class by adding the following line of code: app = Flask(__name__)
  7. The __name__ parameter is a special Python variable that gets the name of the current module.

  8. Define a route:

  9. Use the @app.route decorator to define a route for your application.
  10. For example, to define a route that displays "Hello from Flask" when the user visits the root URL, add the following code: @app.route('/') def hello(): return 'Hello from Flask'

  11. Run the application:

  12. At the end of your script, add the following lines of code to run the Flask application: if __name__ == '__main__': app.run()
  13. The if __name__ == '__main__': condition ensures that the Flask application is only run if the script is executed directly (not imported as a module).

  14. Execute the script:

  15. Save the script with a .py extension, for example, app.py.
  16. Open your terminal or command prompt and navigate to the directory where the script is saved.
  17. Run the script by executing the command: python app.py
  18. You should see output indicating that the Flask application is running, typically on http://127.0.0.1:5000/ or http://localhost:5000/.

  19. Test the application:

  20. Open a web browser and visit the URL where the Flask application is running.
  21. In this case, visit http://127.0.0.1:5000/ or http://localhost:5000/.
  22. You should see the message "Hello from Flask" displayed on the webpage.

By following these steps, you should be able to create a Flask application that displays "Hello from Flask" when accessed through a web browser.
