Python focus: 𝗢𝗯𝗷𝗲𝗰𝘁 𝗢𝗿𝗶𝗲𝗻𝘁𝗲𝗱 𝗣𝗿𝗼𝗴𝗿𝗮𝗺𝗺𝗶𝗻𝗴 (𝗢𝗢𝗣𝘀), specifically 𝗖𝗹𝗮𝘀𝘀𝗲𝘀 𝗮𝗻𝗱 𝗢𝗯𝗷𝗲𝗰𝘁𝘀. I worked on the same problem in two ways. First, without using classes, and then using a class-based approach. That comparison made the purpose of OOP very clear. What I practiced: • Solving a real problem using plain dictionaries and functions • Calculating average score and age of players without classes • Identifying repetition and tightly coupled logic in the non-OOP approach Then rewriting the same logic using OOP: • Defining a class as a blueprint for a cricket player • Creating objects as individual player instances • Using the 𝗶𝗻𝗶𝘁 method to initialize object properties • Separating data attributes and behavior into one structure • Adding methods for calculating average score and age • Using class attributes and instance attributes correctly • Implementing 𝘀𝘁𝗿 for clean object representation 𝗞𝗲𝘆 𝘁𝗮𝗸𝗲𝗮𝘄𝗮𝘆𝘀: • Classes act as blueprints, objects are real instances • OOP helps organize data and behavior together • Code becomes cleaner, reusable, and easier to maintain • Adding new players or features becomes straightforward • Methods define what an object can do, not just what it stores Working on the same problem with and without classes showed why OOP matters in larger projects. It is not about writing more code. It is about writing structured and scalable code. If you are learning Python, how did OOP click for you when you first encountered it? #Python #PythonLearning #OOPs #ClassesAndObjects #ProgrammingBasics #LearningInPublic #DataAnalytics #Upskilling

🚀 OOPS Concepts in Python – Explained Simply! Object-Oriented Programming (OOPS) helps us design programs using real-world concepts, making code modular, reusable, and easy to maintain by using classes and objects. 🔑 Core OOPS Concepts in Python: 1️⃣ Class A blueprint for creating objects. 👉 Defines attributes and methods. 2️⃣ Object An instance of a class that represents a real-world entity. 👉 Example: student = Student(). 3️⃣ Attributes Variables that store object data. 👉 Example: name, age, salary ✔ Describe the state of an object. 4️⃣ Constructor (__init__) A special method that runs automatically when an object is created. 👉 Used to initialize attributes. ✔ Ensures objects start with valid data. 5️⃣ Encapsulation Wrapping data (attributes) and methods into a single unit (class). ✔ Improves security and control. 6️⃣ Inheritance Allows one class to inherit properties and methods from another class. ✔ Promotes code reusability. 7️⃣ Polymorphism Same method name, different behavior. ✔ Increases flexibility in programs. 8️⃣ Abstraction Hides implementation details and shows only essential features. ✔ Focus on what the object does, not how. 💡 Why OOPS in Python? ✔ Cleaner code ✔ Easy maintenance ✔ Scalable applications ✔ Real-world problem solving 📌 tomorrow post about inheritance and its types with solved examples. #Python #PythonBasics #LearnPython #CodingJourney #ProgrammingForBeginners #LinkedInLearning #10000coders #ManivardhanJakka

A few friends and I decided to start a 100-day Python challenge today — February 2nd. Not January 1st. Not a New Year resolution. Because growth isn’t about the calendar. It’s about the moment you see the light and choose to walk toward it. Now, to business. For Day 1, I decided not to write fancy code or build visuals. Instead, I focused on something many of us use daily but rarely question: Why do Python “requirements” matter? Let’s talk about pip. pip is Python’s package installer. It allows us to install external libraries that power our work — from running SQL inside Python, to exporting notebooks as HTML or PDF, to building dashboards and automations. But here’s the thing: If a package’s requirements aren’t met, your work stops. You’ve probably seen it before: • You run !pip install … • You get blocked by dependency issues • Errors start flying (sometimes 500-level errors) • Progress? Paused. Why? Because that package may depend on specific versions of other libraries. Even if it’s outdated, Python needs those dependencies satisfied to execute your task correctly. So no — pip isn’t being difficult. It’s enforcing structure, compatibility, and reliability. And that’s the lesson. Understanding how to code is powerful. Understanding why things work the way they do is what gives you control. This curiosity — questioning tools, systems, and assumptions — is exactly what drives sustainable learning and innovation, aligning closely with SDG 4: Quality Education and capacity building through technical skills. If you’re a Python programmer (in any field) and you’d like to join our 100-day challenge, feel free to jump in. Tag me in your work — let’s grow a community of learners building, failing, and learning together. Because in the end, the person who understands the WHY owns the power. #python #dataanalysis #healthanalyst

Python doesn’t just run code — it decides what to run next… just like we do. When you first learn to code, it feels magical: you write a few lines, hit run, and something happens. But a real program doesn’t just go top to bottom — it needs to think, react, and choose based on conditions, just like human decision making in everyday life. In my latest article, I break down how Python “thinks” with control flow, showing how constructs like if, else, and logical conditions let your code behave intelligently — not just sequentially. 👇 Here’s what you’ll learn: 🔹 What control flow really means It’s not just syntax — it’s how Python evaluates conditions and chooses actions like humans do. 🔹 Why programs need decision logic Without it, your code would just follow instructions blindly — and that’s not very useful for dynamic tasks. 🔹 How if, else, and chained conditions work together These are the structures that allow your Python programs to adapt to different scenarios and inputs. 🔹 Real-life analogy to human thinking Just like carrying an umbrella if it’s raining, Python evaluates “conditions” and chooses what to do next — making your programs flexible and responsive. Whether you’re just starting your Python journey or building data pipelines, ML systems, or automation tools, understanding how Python decides is foundational to writing smarter code. 👉 I’ll drop the article link in the first comment — check it out and let me know this: What’s one decision your code has to make often? Is it based on user input, data values, or something else? 👇 #Python #Programming #ControlFlow #DecisionMaking #Coding #DataScience #TechLearning

Top Python Libraries in 2025: General‑Use Tools That Raise the Bar Python’s general‑purpose tooling in 2025 shows a clear push toward speed, clarity, and production safety. A new wave of Rust‑powered tools like ty and complexipy focuses on making everyday development feedback fast enough to feel invisible, while grounding quality metrics in how humans actually read and understand code. The result is tooling that helps teams move faster without sacrificing maintainability. Developer productivity and correctness are a strong theme. ty rethinks Python type checking with fine‑grained incremental analysis and a “gradual guarantee” that makes typing easier to adopt at scale. Complexipy complements this by measuring cognitive complexity instead of abstract execution paths, helping teams identify code that’s genuinely hard to understand rather than just mathematically complex. Several tools address long‑standing infrastructure pain points. Throttled‑py modernizes rate limiting with multiple algorithms, async support, and strong performance characteristics, while Httptap makes HTTP performance debugging concrete with waterfall views that reveal where latency actually comes from. These libraries focus on observability and control where production systems usually hurt the most. Security, code health, and extensibility also get serious attention. FastAPI Guard consolidates common API security concerns into a single middleware, while Skylos tackles dead code and potential vulnerabilities with confidence scoring that respects Python’s dynamic nature. Modshim offers a powerful alternative to monkey‑patching, allowing teams to extend third‑party libraries cleanly without forking or global side effects. Finally, there’s a clear move toward better interfaces and specifications. Spec Kit reframes AI‑assisted coding around executable specs instead of vague prompts, while FastOpenAPI brings FastAPI‑style documentation and validation to multiple frameworks without forcing a rewrite. Together, these libraries show a Python ecosystem that’s maturing—not by adding more abstractions, but by making the fundamentals faster, safer, and easier to reason about.
