Above code is used to run the whole application. Basic functions related to flask framework is explained in my previous tutorial. Hope now you aware of it. When you click send button in ideamart simulator it will send a post request to the URL [5] that is mentioned above. As you can see in the program that request is handled by the function named as sms_receiver. The request message is taken as a variable called ideamart_message. After that, It is split into parts and send the response back to URL [6].
from flask import *
app = Flask(__name__)
@app.route('/')
def hello_world():
return render_template("index.html")
if __name__ == '__main__':
app.run(host="localhost", port=5000)
In the first line flask library is imported. Then the second line is to initiate the application. That means create a Flask instance, in your main module. The idea of the first parameter is to give Flask an idea what belongs to your application. This name is used to find resources on the file system, can be used by extensions to improve debugging information and a lot more. The next line is connected a URL rule. Simply we can say when a request came to the "/" URL it will render "index.html" which is located in the template folder. The next line is to start the application. Host and port values are configured in the program itself. Hope you understand the tutorial. Likewise, We can create a web application using python flask in less amount of time and also you can create more advance applications using python.
