1. Basic try-except Block python # Basic exception handlingtry: num = int(input(“Enter a number: “)) result = 10 / num print(f”Result: {result}”)except: print(“Something went wrong!”) Example 1: Division with Zero Handling python # Handling division by zero error try: num1 = int(input(“Enter first number: “)) num2 = int(input(“Enter second number: “)) result = num1 /…

Exception handling in Python is a process of responding to and managing errors that occur during a program’s execution, allowing the program to continue running without crashing. These errors, known as exceptions, disrupt the normal flow of the program and can be caught and dealt with using a try…except block. How It Works The core…

Lambda Functions in Python Lambda functions are small, anonymous functions defined using the lambda keyword. They can take any number of arguments but can only have one expression. Basic Syntax python lambda arguments: expression Simple Examples 1. Basic Lambda Function python # Regular function def add(x, y): return x + y # Equivalent lambda function add_lambda =…

Decorators in Python A decorator is a function that modifies the behavior of another function without permanently modifying it. Decorators are a powerful tool that use closure functions. Basic Concept A decorator: Simple Example python def simple_decorator(func): def wrapper(): print(“Something is happening before the function is called.”) func() print(“Something is happening after the function is…

Closure Functions in Python A closure is a function that remembers values from its enclosing lexical scope even when the program flow is no longer in that scope. Simple Example python def outer_function(x): # This is the enclosing scope def inner_function(y): # inner_function can access ‘x’ from outer_function’s scope return x + y return inner_function…

Understanding Functions Returning Functions In Python, functions can return other functions, which is a powerful feature of functional programming. Basic Example python def outer(): def inner(): print(“Welcome!”) return inner # Return the inner function (without calling it) # Calling outer() returns the inner function f = outer() # f now refers to the inner function…

Functions as Parameters in Python In Python, functions are first-class objects, which means they can be: Basic Concept When we pass a function as a parameter, we’re essentially allowing one function to use another function’s behavior. Simple Examples Example 1: Basic Function as Parameter python def greet(name): return f”Hello, {name}!” def farewell(name): return f”Goodbye, {name}!” def…

Functions as Objects and First-Class Functions in Python In Python, functions are first-class objects, which means they can be: 1. Functions as Objects In Python, everything is an object, including functions. When you define a function, you’re creating a function object. python def greet(name): return f”Hello, {name}!” # The function is an object with type ‘function’…

python Enhanced Password Strength Checker python import re def is_strong(password): “”” Check if a password is strong based on multiple criteria. Returns (is_valid, message) tuple. “”” # Define criteria and error messages criteria = [ { ‘check’: len(password) >= 8, ‘message’: “at least 8 characters” }, { ‘check’: bool(re.search(r'[A-Z]’, password)), ‘message’: “one uppercase letter (A-Z)”…
