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)”…

Python Program to Check Pangram Phrases What is a Pangram? A pangram is a sentence or phrase that contains every letter of the alphabet at least once. Method 1: Using Set Operations python def is_pangram_set(phrase): “”” Check if a phrase is a pangram using set operations “”” # Convert to lowercase and remove non-alphabetic characters…

Python Modules: Creation and Usage Guide What are Modules in Python? Modules are simply Python files (with a .py extension) that contain Python code, including: They help you organize your code into logical units and promote code reusability. Creating a Module 1. Basic Module Creation Create a file named mymodule.py: python # mymodule.py def greet(name): return f”Hello, {name}!”…

1. sorted() Description: Returns a new sorted list from the items in iterable. python # 1. Sort list of numbers numbers = [3, 1, 4, 1, 5, 9, 2] print(sorted(numbers)) # [1, 1, 2, 3, 4, 5, 9] # 2. Sort list of strings fruits = [“banana”, “apple”, “cherry”] print(sorted(fruits)) # [‘apple’, ‘banana’, ‘cherry’] # 3….

1. type() Description: Returns the type of an object. python # 1. Basic types print(type(5)) # <class ‘int’> print(type(3.14)) # <class ‘float’> print(type(“hello”)) # <class ‘str’> print(type(True)) # <class ‘bool’> # 2. Collection types print(type([1, 2, 3])) # <class ‘list’> print(type((1, 2, 3))) # <class ‘tuple’> print(type({1, 2, 3})) # <class ‘set’> print(type({“a”: 1})) # <class…
