Python Class & Object Tutorial


In general a class is defined as grouping of objects having identical properties, common behavior, and shared some relationships to perform a specified task. For example, a computer system, a vehicle etc.

But in programming point of view a class is a user-defined data type which fully defines an object. That means without a class, we cant declare an object

An object is also called an instance of a class and the process of creating this object is known as instantiation.

Once a class is declared, we can declare any no of objects belonging to that class.

Syntax to declare an object: object_name=class_name()


Example-1:

Example-2:

Note:
When we define a function inside a class, it is mandatory to pass a self keyword as parameter to function. The self keyword act as a pointer which points to the current instance(object). That means what ever the object contains data, that data member will access by self keyword using dot operator.

Python Function Basics Tutorial

Python Function: A function is a block of code to perform a specified task. In this context, there is a function call and there is a function definition. When a function is calling then the function definition is executing. We can pass data known as parameters(arguments) into a function. At the time of function call whatever we take arguments, is known as actual arguments and at the time of function call, we take arguments is known as formal arguments. Here actual arguments equals to the formal arguments. A function can return a value as result. In python a function is defined by using def keyword. Example(without arguments): def show():     #function definition     print('python means SILAN Technology') show()      #function call output: python means SILAN Technology Example(with arguments) def area(base,height):      #function definition     a=...
