Agile Methodology in SPM Definition: Agile methodology is a software development approach in which the project is divided into small parts and developed iteratively and incrementally , with continuous customer feedback and improvement. Adapting to Scrum helps organizations become more flexible and efficient. By following Scrum practices, teams can deliver high-quality software quickly and effectively. Principles of Agile Agile follows the ideas of the Agile Manifesto , which emphasize: Customer satisfaction through early delivery Welcome changing requirements Frequent delivery of working software Close collaboration between team members Focus on simplicity and efficiency Agile Process Requirement Analysis – Collect and prioritize user requirements Planning – Divide work into small units called user stories Iteration/Sprint – Develop features in short cycles (1–4 weeks) Development & Testing – Coding and testing happen together R...

  First-Class Functions in Python  🔍 What are First-Class Functions in Python? In Python , first-class functions mean that functions are treated like any other object (such as integers, strings, or lists). 👉 This allows functions to: Be assigned to variables Be passed as arguments Be returned from other functions Be stored in data structures ✨ Why are First-Class Functions Important? ✅ Enables functional programming ✅ Makes code flexible and reusable ✅ Helps in writing clean and modular programs ✅ Used in advanced concepts like decorators and closures 🧠 Key Characteristics of First-Class Functions ✔ 1. Assign Function to a Variable def greet (): return "Hello, Python!" say_hello = greet print ( say_hello ()) ✔ 2. Pass Function as an Argument def add ( a , b ): return a + b def operate ( func , x , y ): return func ( x , y ) print ( operate ( add , 5 , 3 )) ✔ 3. Return Function from Another Function def outer (): ...

  *args and **kwargs in Python  🔍 What are *args and **kwargs in Python? In Python , *args and **kwargs allow you to pass a variable number of arguments to a function. 👉 *args → accepts multiple positional arguments 👉 **kwargs → accepts multiple keyword arguments ✨ Why Use *args and **kwargs? ✅ Makes functions flexible ✅ Handles unknown number of inputs ✅ Useful in real-world applications ✅ Reduces code repetition 🧠 Understanding *args (Non-keyword Arguments) *args allows a function to accept any number of positional arguments. 📌 Example: def add_numbers ( * args ): total = 0 for num in args : total += num return total print ( add_numbers ( 1 , 2 , 3 , 4 )) 👉 Output: 10 🔍 How *args Works *args collects arguments into a tuple You can loop through it like a list def show_args ( * args ): print ( args ) show_args ( 10 , 20 , 30 ) 👉 Output: (10, 20, 30) 🧠 Understanding **kwargs (Keyword Ar...

  Returning Functions from Functions in Python   🔍 What Does “Returning Functions from Functions” Mean? In Python , functions are first-class objects . This means a function can return another function as its result. 👉 In simple terms, one function creates and returns another function. ✨ Why Return Functions? ✅ Enables dynamic behavior ✅ Used in decorators ✅ Helps in functional programming ✅ Improves code flexibility and reusability 🧠 Basic Syntax def outer_function (): def inner_function (): return "Hello from inner function" return inner_function 📌 Simple Example def outer (): def inner (): return "Hello, Python!" return inner # Get the returned function my_func = outer () print ( my_func ()) 👉 Output: Hello, Python! 🔢 Example with Parameters def multiplier ( n ): def multiply ( x ): return x * n return multiply # Create a function double = multiplier ( 2 ) triple =...
