The __init__() Method in Python What is the __init__() Method? The __init__() method is a special method in Python known as the constructor. It is automatically called when a new instance of a class is created. Its primary role is to initialize the attributes of the object with the values provided during the creation of […]

Creating and Working with Objects in Python What is an Object? In Python, an object is an instance of a class. When you create an object, you are creating an instance of a class with its own unique set of attributes and methods. An object represents a specific realization of a class. Creating an Object

Creating Classes in Python Introduction In Python, classes are a way to bundle data and functionality together. Creating classes and instances (objects) is a key part of object-oriented programming (OOP). Below is a detailed guide on how to create classes, including various features and methods. Defining a Class To define a class in Python, use

Lambda Functions Introduction to Lambda Functions Lambda functions in Python are small, anonymous functions defined with the lambda keyword. They allow you to create functions in a concise way, especially for simple operations where defining a full function might seem excessive. Syntax: lambda arguments: expression arguments: The input parameters for the function. expression: An expression

Boolean Functions in Python bool() The bool() function converts a value to a boolean (True or False). It’s useful for checking the truthiness of a value in different contexts. Syntax: bool([value]) Returns: True or False Examples: print(bool(None)) # Outputs: False print(bool(0)) # Outputs: False print(bool(“”)) # Outputs: False print(bool([])) # Outputs: False print(bool(1)) # Outputs:

Value and Variable Evaluation in Python Boolean Contexts In Python, certain values and variables are evaluated in a boolean context, such as in conditional statements (if, while, etc.), logical operations, or when converting to booleans using the bool() function. Understanding how different values evaluate to True or False is crucial for writing correct and efficient

Boolean Values In Python, boolean values are used to represent truth values and are fundamental for conditional statements and logical operations. There are two boolean constants: True: Represents truth or a condition that is met. False: Represents falsity or a condition that is not met. In Python, booleans are a subclass of integers, meaning they

Operator Precedence in Python In Python, operator precedence determines the order in which operators are evaluated in an expression. Operators with higher precedence are evaluated before those with lower precedence. Here’s a detailed list of operators, from highest to lowest precedence, along with examples to illustrate their use. Parentheses (()) Parentheses have the highest precedence

Join sets in Python Introduction to Sets in Python In Python, a set is an unordered collection of unique elements. Sets are created using the set class. They are useful for performing mathematical operations such as union, intersection, difference, and symmetric difference. Creating a Set # Creating two sets set1 = {1, 2, 3, 4,
