Flask in a Flash: Learn in 6 Minutes 🔥

Flask is a lightweight and flexible web framework for Python that makes it easy to create web applications quickly and efficiently. In this tutorial, I will walk you through the basic steps to set up a simple Flask application in just 6 minutes. Let’s get started!

Step 1: Install Flask
First, you need to install Flask. You can do this by using pip, which is the package installer for Python. Open up your terminal and run the following command:

pip install Flask

Step 2: Create a new Python file
Next, create a new Python file for your Flask application. You can name this file anything you like, but for this tutorial, let’s name it app.py.

Step 3: Import Flask and create an app instance
In your app.py file, import the Flask class and create an instance of the Flask application:

from flask import Flask

app = Flask(__name__)

Step 4: Create a route
Now, let’s create a simple route that will return a "Hello, World!" message when someone visits the root URL of your application:

@app.route('/')
def hello():
    return 'Hello, World!'

Step 5: Run the Flask application
To run your Flask application, add the following lines of code at the bottom of your app.py file:

if __name__ == '__main__':
    app.run()

Now, open up your terminal, navigate to the directory where your app.py file is located, and run the following command:

python app.py

This will start the Flask development server, and you should see a message saying that your application is running on http://127.0.0.1:5000/. Open up your web browser and go to this URL to see your "Hello, World!" message displayed.

Step 6: Conclusion
Congratulations! You have successfully set up a simple Flask application in just 6 minutes. Flask is a powerful and versatile web framework that allows you to build web applications quickly and easily. There are many more features and functionalities that Flask offers, so I encourage you to explore the Flask documentation to learn more about what you can do with this framework.

That’s it for this tutorial. I hope you found it helpful and that you are now ready to start building awesome web applications with Flask. Happy coding! 🔥
