Step 13. Handle user’s input:- So here we’ve created another folder called “pdf” and inside that we’ve created another file called Index.js in which we’ve written this function called ” getQuotation ” to transform data as per our needs. Step 14. Create invoice Here we’ll be writing createInvoice.js file inside pdf folder and we’ll using
To continue from where we left over- Step8. Setting up our webhook:- Now we’ll shell out our serverless webhook function so that we can progressively build on it as we go along by typing below command- This will create a nodejs boiler plate . “path” in above command simply means ” path to the folder
Introduction:- In this post we’ll solve POC in which “MachineLearning-made-easy.com” wishes to use WhatsApp Bot to generate invoices for its client. WhatsApp Bot should also be able to send these invoices to respective clients. So stay tuned to check this project in my next post. Step 1. Creating an agent on Dialogflow:- Create a new
Iterators :- An iterator is an object that can be iterated upon, meaning that you can traverse through all the values. Technically, in Python, an iterator is an object which implements the iterator protocol, which consist of the methods __iter__() and __next__(). To create a Python iterator object, you will need to implement two methods in your iterator
What is Composition:- As the name implies , In composition one of the classes is “composed” of one or more instance of other classes. In other words one class is container and other class is content and if you delete the container object then all of its contents objects are also deleted. Composition models a “has a” relationship
Introduction:- If you want to understand the python super function, we need to know about Inheritance in Python language. In Python Inheritance, Inheritance is the concept in object-oriented programming in which a class derives (or inherits) attributes and behaviors from another class without needing to implement them again.

Introduction Encapsulation is one of the fundamental aspects of Object Oriented Programming. Encapsulation serves to protect the data stored within your objects and provides control and conventions for how you should handle the flow of data in and out of classes. Python does not have the private keyword, unlike some other object oriented languages, but
Introduction A lot of people learn object-oriented programming with languages like C++ and Java. And while they learn, they’re told over and over again that encapsulation is one of the key principles of object-oriented paradigm and that they should take advantage of it. In C++ and Java, things are pretty straight-forward. There are 3 magical and easy
Introduction:- One of the major advantages of Object Oriented Programming is re-use. Inheritance is one of the mechanisms to achieve it. In inheritance, a class (usually called superclass/parent class) is inherited by another class (usually called subclass/child class/derived class). The subclass adds some attributes to superclass. In inheritance, the child class acquires the properties and
