![]() ![]() While trying to print employees fullname, you could either do this-> (emp_1.fullname()) or you could try (Employee.fullname(emp_1)), they both mean the-same thing, in-fact the later is what happens in the background when you run the program. from turtle import Turtle tess Turtle() Instantiate objects of type. Below is the full source code for the piece. Python is an object-oriented programming language, which means that it provides. That is it for class and instance of a class creation. Now suppose we want to print each users fullname, we could actually use the format function in python to concatenate strings to get the fullname, but this would require doing this every time we want to print an employees fullname, but to better enjoy the advantage of code re-use, we would be creating a method to help us generate each employees fullname. On running this script (emp_1) would be passed into the (init) method as self. With that done, when we create our employee, the instance would be passed in automatically, all we would bother ourselves with would be to provide the employee attributes. Next stop we would be looking at setting the instance. ![]() iter (iterable) method that is called for the initialization of an iterator. It uses the next () method for iteration. The iterator object is initialized using the iter () method. The init method after creation receives an instance automatically called ( self), and we also pass in other attributes of the Employee class like name and pay. Iterator in python is an object that is used to iterate over iterable objects like lists, tuples, dicts, and sets. But python allows you to be able to create instances automatically and this we could do using its ( init) method. Imagine a situation we have 1000 employees to create, trying to set the variables each time we want to create an employee would mean having a-lot of code and errors. To create instance variables for each employee we would do the following: Instance variables contain data that is unique to the instance alone. They above code shows the creation of unique instances of the Employee class and to assign data to this instances we would be using instance variables. A class is a blue print for creating instances and each unique employee that we create would be an instance of that class. The above code snippet shows how to create a class in python, the pass keyword under tells python to neglect the class, without this keyword, python would see the class as an empty one and return an error. Now lets have a head first attempt at creating and instantiating a class. To help us understand this better we would be creating an employee class, each employee would have attributes like name,email,pay,etc. Today we would be looking at class creation and instantiation. Last month i started taking a course on python and i stumbled on a tutorial on object oriented programming from the python perspective, and through out this week and coming weeks i would be sharing what i have been able to learn. ![]()
