Flask for beginners: Create Real World Interactive Apps
Flask is a Python framework for building lightweight and dynamic web applications. It helps speed up tedious behind-the-scenes development work, such as URL mapping, and offers more control to the developer to build applications . This course provides the training and hands-on examples and as called Flask for beginners: Create Real World Interactive Apps.
It makes you to get started quickly. We will create two complete interactive web applications and also deploy them to the cloud so others can interact with them. You will learn skills that professional web developers use.
what is flask and where it is used ?
Flask is a web framework for Python. It is a micro framework that doesn’t include an ORM (Object Relational Manager) or such features. It is a WSGI web app framework.
Flask is easy to get started with and is a great choice for small to medium sized projects.
Flask is used to build web applications, RESTful APIs, and other types of applications that need to serve web content.
Flask provides a minimal and flexible interface that allows developers to build their application as they like.
With Flask, you can build simple prototypes quickly, as well as more complex applications with a large number of features.
Flask is widely used in the industry and has a large community of developers who contribute to the framework and write extensions to add additional functionality.
Here is a simple example of how you could design a Flask app:
from flask import Flask, request app = Flask(__name__) @app.route("/") def index(): return "Hello, World!" @app.route("/post", methods=["POST"]) def post(): json_data = request.get_json() return json_data["message"] if __name__ == "__main__": app.run(debug=True)
This is a basic Flask app that has two routes:
/ route returns the string
"Hello, World!" when a GET request is made to it. The
/post route accepts a POST request and returns the
message field from the JSON data in the request body.
This example can be run using the following command:
export FLASK_APP=app.py flask run
