include in flask

To include Flask in your project, follow these steps:

  1. Install Flask: Open your command prompt or terminal and use the following command to install Flask:
pip install flask

This will download and install Flask on your system.

  1. Import Flask: In your Python script, import the Flask module by adding the following line at the beginning:
from flask import Flask

This imports the Flask class that we will use to create our Flask application.

  1. Create an instance of Flask: After importing Flask, create an instance of the Flask class by adding the following line:
app = Flask(__name__)

The __name__ parameter is a special Python variable that represents the name of the current module. It is used by Flask to locate resources such as templates and static files.

  1. Define routes: Routes define the URLs that the application will respond to. To define a route, use the @app.route() decorator followed by the URL pattern. For example:
def home():
    return 'Hello, World!'

In this example, the home function is associated with the root URL ("/"). When a user visits the root URL, the function will be executed and the string "Hello, World!" will be returned.

  1. Run the application: To run the Flask application, add the following lines at the end of your script:
if __name__ == '__main__':

This block of code ensures that the application is only run if the script is executed directly, not when it is imported as a module.

That's it! You have successfully included Flask in your project. You can now start building your web application using the Flask framework.
