Overview
Hey folks, Flask is a powerful web development framework that you can use to build amazing websites. It’s simple, lightweight, and easy to learn, making it the perfect choice for new developers.
In this post, we’ll explore some of the reasons why learning Flask is a good idea, and we’ll look at some of the things you can do with it. So if you’re thinking about getting into web development, or if you’re just curious about Flask, keep reading!
Why Learn Flask?
Python is a powerful, general-purpose programming language used by novices and scientific researchers. It’s also an excellent choice for software engineers who want to get into web development because it has features not found in other languages like Flask which allows you to build fully-featured applications with ease!
Flask is a popular Python framework for developing web applications. It comes with minimal built-in functionalities and requirements, making it simple to get started but still flexible enough that developers have the liberty of customizing most aspects including database integration or accounts & authentication.
Django v/s Flask: Which is better?
If you don’t know what is Django and If you’re looking for a way to get started with Django, look no further than this article. Let’s explore Django.
Both are excellent web development frameworks, and each has its own strengths and weaknesses.
Using Flask to build your website is the best option if you want a granular level of control and cannot rely on an extensive community.
With the REST Framework, you can build powerful APIs with Django. Flask requires more work so there’s an increased chance for mistakes to be made.
The best way to decide which framework fits your project style is by building a few basic CRUD apps with both frameworks and seeing what you like better.
Introduction to Flask
Creating Flask App Object
# Import Flask class from flask import Flask # Create Flask object app = Flask(__name__)
Import flask class and create flask object.
Running Flask App
Open your terminal and run python app.py (where app.py is our file name)
Creating a Route
@app.route('/')
def hello_world():
return 'Hello World!'Routes in a Flask app can be created by defining view functions and associating URLs with them using the route() decorator. They specify how your website handles requests it receives, such as what information to display on each page at certain URLs.
Returning HTML From Route
@app.route('/')
def hello_world():
return '<h1>Hello, World!</h1>'Using Flask, we can return HTML from a view function to be rendered on our webpage.
Let’s create a Hello World webpage using Flask
from flask import Flask
app = Flask(__name__)
@app.route('/')
def index():
return '<h1>Hello World</h1>'
app.run(debug=true)Flask by default runs on port number 5000, you can change it (app.run(port=0.0.0.0)). For running this program open cmd or terminal in the same folder and type python app.py where ‘app’ is your filename.
After running the server, open any browser and then head to localhost:5000/. You’ll see that there is a Hello World page waiting for you!
This is not a full tutorial, but I hope now you understand why Flask is a great web development framework to learn and how easy it is to get started.
