Build Your Dynamic Website with Flask
In this guide, I’ll walk you through how to create a simple but robust dynamic website using Flask, a popular micro web framework written in Python. It’s powerful, flexible, and perfect for small-scale projects.
Step 1: Install Flask
To kickstart this adventure, we need to install Flask. In your terminal, type pip install flask. After installing Flask, create a new Python file, and name it app.py. The ‘.py’ extension stands for Python.
Step 2: Creating a Flask Web Server
In your app.py file, input the following codes:
from flask import Flask
app = Flask(__name__)
@app.route("/")
def home():
return 'Hello, world!'
if __name__ == "__main__":
app.run()
In the context above, Flask is setting up a route at the home page of the web server, and when we navigate to the home page, it returns ‘Hello, world!’.
Step 3: Adding Dynamic Content
But our focus is to create a dynamic website. So, let’s add some dynamic content using dynamic routes. We’ll introduce Flask’s variable rules:
@app.route('/user/
def show_user_profile(username):
return 'User %s' % username
Step 4: Run Your Server
Finally, let’s run our Flask application. In the terminal, type python app.py and open a web browser. Navigate to http://127.0.0.1:5000/, and you should see our ‘Hello, world!’.
Now, instead try http://127.0.0.1:5000/user/John. You should see ‘User John’. That’s pretty cool, huh?
- Flask lets you build dynamic websites very quickly and easily.
- Understanding how Flask’s routing operates is essential.
- Experiment and try to build more complex apps with Flask!
Conclusion
This 1-page guide introduces you to building a dynamic website with Flask. Flask is versatile enough for professional development yet simple enough for beginners. Ultimately, its dynamic nature is what makes it so powerful. Remember, the key to mastery is consistent practice. Stay curious and keep coding!
