Exception handling is a mechanism in Python that deals with runtime errors, allowing the program to continue execution or handle errors gracefully. It is an essential tool for making Python applications robust and error-resistant. Definition An exception is an event... Read more
In Python, abstract classes and interfaces are primarily used to define a blueprint for other classes. They allow you to create a common structure for classes while enforcing specific methods to be implemented in subclasses. For example, if you want... Read more
Polymorphism is an object-oriented programming concept that means “one function, many forms”. In Python, it allows the same method name to be used for different types of objects, and the behavior will depend on the object’s class. Examples of Polymorphism:... Read more
Inheritance is a core principle in OOPs (Object-Oriented Programming) that enables a child class or derived class to inherit properties and methods from a base class or parent class. This greatly encourages code reuse and creates a hierarchical structure among... Read more
Object-oriented programming (OOP) is a programming paradigm that centers software design around data, represented as objects, rather than focusing primarily on functions and logic. In OOPs, objects are instances of classes, which can encapsulate data and behaviors. The primary aim... Read more
Indexing To access the individual elements in a sequential data types like a string, list, or tuple using their index position. In Python, the indexing number starts from 0 for the first element. Two types of indexing Syntax: sequence[index_number] Example:... Read more
Data types are used to define the type of data or value stored in a variable. They determine how the data is stored, processed, and manipulated in a program. Based on the value provided, the data type will be assigned... Read more
In Python, input and output operations are crucial for engaging with the end user and processing data. Input is used to receive data from the user or other sources, while output is used to display data to the end user... Read more
A variable is a name of a memory location that temporarily stores data. Which can be used and modified during a program’s execution. Characteristics of Variables in Python Assigning Values to Variables You can assign a value to a variable(s)... Read more
Keywords in Python are reserved words that hold special predefined meanings and form the foundation of the language’s syntax. They cannot be used as identifiers, including variable names, function names, or any other custom labels. There are 35 keywords. Table... Read more
