Python

Polymorphism is a core concept in object-oriented programming (OOP) that allows objects of different classes to be treated as objects of a common superclass. It simplifies programming by enabling a single interface to operate on different types of data. The term polymorphism comes from Greek, meaning “many forms,” and in Python, it allows methods, operators … Read more

What is an Iterator? An iterator is an object in Python that contains a sequence of elements and provides a mechanism to traverse through them one at a time. It implements two key methods: Understanding Iteration Protocol Python’s iteration protocol is a set of rules that govern how objects behave during iteration. It requires two … Read more

Why Use Inheritance in Python? Defining Inheritance in Python A child class is created by passing the parent class as an argument in parentheses during its definition. Syntax: class ParentClass: # Parent class contentclass ChildClass(ParentClass): # Child class content Examples of Inheritance Basic Example class Animal: def sound(self): print(“This animal makes a sound”)class Dog(Animal): def … Read more

What Are Classes and Objects in Python? Analogy Think of a class as a blueprint for a house. The blueprint specifies what the house will look like (attributes) and how it will function (methods). An object is the actual house built using that blueprint. Syntax for Defining a Class class ClassName: # Class attributes and … Read more

What are Arrays in Python? An array is a collection of items stored at contiguous memory locations. In Python, arrays are managed using the array module or third-party libraries like NumPy for more advanced operations. Unlike lists, arrays in Python require all elements to be of the same type, which makes them more memory-efficient for … Read more

What are Lambda Functions in Python? A lambda function is a small, anonymous function defined using the lambda keyword. These functions do not require a name and are often used for small, simple operations. Lambda functions are also referred to as inline functions or anonymous functions because they are created without a formal def keyword … Read more

What is a Function in Python? A function is a block of reusable code that performs a specific task. Functions allow you to write modular code by encapsulating functionality into separate blocks, which can then be called multiple times within your program. Benefits of Using Functions Syntax of a Python Function The def keyword is … Read more

What is a For Loop in Python? A Python for loop is used to iterate over sequences like lists, tuples, strings, dictionaries, or even ranges of numbers. Unlike some other languages where for loops iterate using counters, Python’s for loop works directly with elements in a sequence. Why Use For Loops? Syntax of a For … Read more

What is a While Loop in Python? A while loop executes a block of code as long as a specified condition evaluates to True. It checks the condition at the beginning of each iteration. Why Use While Loops? Syntax of a While Loop while condition: # Code to execute as long as the condition is … Read more

What are Python If…Else Statements? The if…else construct in Python executes a block of code if a specified condition is True. If the condition evaluates to False, the code in the else block will run. Why Use If…Else Statements? Syntax of If…Else Statements If Statement: Executes a block of code if the condition is True. … Read more
