flask is a popular web framework for building web applications in python. in this tutorial, we will guide you through the process of installing flask using the python package manager, pip. additionally, we'll provide a simple code example to help you get started with creating your first flask application.
before you begin, make sure you have python and pip installed on your system. you can download python from the official python website and pip is usually included with python installations.
open a terminal on linux or macos, or a command prompt on windows. this is where you'll execute the commands to install flask.

this command will download and install the latest version of flask and its dependencies.
to verify that flask has been successfully installed, you can run the following command to check the installed version:
this should display the installed flask version.
now that flask is installed, let's create a simple "hello, world!" application.
create a new file named app.py and open it in a text editor. add the following code:
this code creates a minimal flask application. the @app.route('/') decorator defines a route for the root url ("/") and the associated hello_world function will be called when someone accesses that route. the app.run(debug=true) line starts the development server.
save the app.py file and return to the terminal. navigate to the directory where app.py is located and run the following command:
this will start the development server, and you should see output indicating that the server is running. open your web browser and go to http://127.0.0.1:5000/ or http://localhost:5000/. you should see the "hello, world!" message.
