How to create website using Flask ?

Once you have Python installed, you can use pip, the Python package manager, to install Flask. Open up a terminal and enter the following command:

This will install Flask and all of its dependencies.

Next, we'll create a new Flask project. In your terminal, navigate to the directory where you want to create your project, and create a file called [ app.py ]

In the app.py file, we'll create a Flask app and define a route. A route is a URL path that maps to a Python function. Add the following code to the app.py file:

This creates a Flask app and defines a route for the root URL (/) that returns the string "Hello, World!".

To run the app, enter the following command in the terminal:

This will start the Flask development server, and you should be able to see your app by visiting http://localhost:5000 in a web browser.

Now, let's add some more routes and dynamic content to our app. In the app.py file, add the following code:

This creates a new route that takes a dynamic parameter called name and returns a personalized greeting. You can test this route by visiting http://localhost:5000/hello/<name>, where <name> is a placeholder for the actual name you want to use.

Next, we'll add a template to our app. Flask uses templates to generate HTML dynamically.

In the templates directory of your project, create a file called index.html and add the following code:

Finally, we'll modify our hello route to use the template. Add the following code to the app.py file:
