We can kick-start our application development with a simple example, which gives you an idea of how we program in Python with a flask framework. In order to write this program, we need to perform the following steps:
Create a WSGI application instance, as every application in Flask needs one to handle requests from the client.
Define a
routemethod which associates a URL and the function which handles it.Activate the application's server.
Here is an example which follows the preceding steps to make a simple application:
from flask import Flask app = Flask(__name__) @app.route("/") def home(): return "Hello Guest!" if __name__ == "__main__": app.run()
In the preceding lines of code, we have created a WSGI application instance using the Flask's Flask class, and then we defined a route which maps the path "/" and the view function home to process the request using a Flask's decorator function Flask.route(). Next, we used the app.run() which tells the server...
