Building APIs with Flask in 3 Easy Steps

Day 13 of my Python Full Stack journey. ✅ Today's topic: Scope — where your variables live and die. This one concept explains so many confusing bugs. Here's what I typed today: # Local scope — only lives inside the function def my_function(): message = "I only exist here" print(message) # works ✅ my_function() # print(message) # ❌ Error! message doesn't exist out here # Global scope — lives everywhere name = "Punith" def greet(): print(f"Hello {name}") # works ✅ greet() # Modifying a global variable inside a function count = 0 def increment(): global count count += 1 increment() print(count) # 1 ✅ Biggest lesson today: Avoid using 'global' too much. If every function is touching the same variable — that's a sign your code needs better structure. This is exactly why functions should take inputs and return outputs — not secretly modify things from outside. Small concept. But this is how senior developers think. #PythonFullStack #Day13 #BuildingInPublic #100DaysOfCode #Bangalore

🚀 Day 5: Mastering Loops in Python One of the biggest strengths of programming is automation — and loops make it possible. Instead of writing repetitive code, loops allow us to execute a block of code multiple times in a clean and efficient way. 🔹 In Python, we mainly use: ✔ for loop Best for iterating over sequences like lists, strings, or ranges ✔ while loop Runs continuously as long as a condition remains True 💡 Example: for i in range(5):     print(i) count = 0 while count < 5:     print(count)     count += 1 🔹 Loop Control Statements: ✔ break → stops the loop immediately ✔ continue → skips the current iteration ✔ pass → acts as a placeholder 📌 Why are loops important? From handling large datasets to building real-world applications, loops are everywhere. They help: ✔ Reduce code repetition ✔ Improve efficiency ✔ Make programs scalable 💡 The more you practice loops, the more you start thinking like a programmer. 📈 Step by step, building strong fundamentals. #Python #Programming #Coding #Developers #BackendDevelopment #LearningJourney #Loops #Django

Day 5 of my Python Full Stack journey. ✅ Today's topic: Functions — write once, use anywhere. This is where Python starts feeling like real programming. Instead of copying the same code 10 times — you wrap it in a function and call it. Here's what I typed today: def greet(name, role="Developer"): return f"Hey {name}, future {role}!" msg = greet("Punith") print(msg) # Output: Hey Punith, future Developer! Biggest lesson today: Default arguments make functions flexible. You only pass them if you want to override the default. Small thing. But it made everything click. — Here's what I covered in 5 days: → Variables & Data Types → Conditionals → Loops → Functions → Built a Calculator from scratch — pushed to GitHub ✅ 45 minutes a day.

🚀 𝐂𝐫𝐞𝐚𝐭𝐞 𝐏𝐨𝐰𝐞𝐫𝐟𝐮𝐥 𝐀𝐏𝐈𝐬 𝐢𝐧 𝐏𝐲𝐭𝐡𝐨𝐧 . APIs are the backbone of every modern application — from mobile apps to large-scale enterprise systems. If you’re serious about backend development, mastering API creation is a must-have skill. In this session, we begin the journey of building REST APIs using Python & Flask, where you’ll learn: ✅ What an API is and how it works ✅ How REST architecture simplifies communication ✅ HTTP methods – GET, POST, PUT & DELETE ✅ CRUD operations in real-time ✅ Structuring clean and scalable Python APIs This is designed to take you from basic concepts to real-world implementation step by step. 👨💻 Learn.

being a Senior Developer is only about 1/3 Python knowledge. The other 60% is the ecosystem. It’s the tooling. It’s all of the tech around Python that makes you stand out from the rest. https://lnkd.in/dcf54mVY

The flasgo website is now live. You want a fast async typed Python web framework that has security built in from the start(follows owasp 2025) requires Python 3.14 and has a small attack surface as possible with django like security primatives but is easy as using flask? Then you have come to the right place. #python #webdevelopment #web

As a #Python developer, there’s a lot more beyond writing code i.e. Isolation -> packaging -> publishing -> distribution. Still using PYTHONPATH and sys.path and calling it a package…? Is virtual environments your only packaging strategy…? Still zipping files and calling it distribution…? You are not alone — most of us have been there. #Python #PythonPackaging #PyPI #PreCommit #DevOps #SoftwareEngineering #CodeQuality #Docker #CI #CD #Ruff #uv

Write code that doesn't break in production...! When building end-to-end pipelines, reading data from GitHub or external URLs is common. But relying on a "happy path" is a mistake. For robust development, always implement: Logging: To track the flow and capture specific error details. Exception Handling: To prevent the entire app from crashing and get clear "Unable to load" alerts. It’s a simple habit, but it’s what separates a beginner from a Pro Developer. #Python #MLOps #CleanCode #SoftwareEngineering #DataScience #CodingTips

We’ve all been there… “Code works perfectly on local” Production: 💥 I wanted to fix that gap — not with theory, but with something practical and repeatable. So I built a production-ready Python service setup: • Docker for consistency • systemd for reliability • Nginx + Blue-Green for zero-downtime deployments The idea was simple: 👉 Your service should never go down during deployment This blog is what I wish I had when I started building real systems. If you’re moving from scripts to production systems, this will help: https://lnkd.in/gZThnvK8 Would love your thoughts 🙌 #DevOps #Python #SystemDesign #Backend #Tech

As a backend developer, I’ve started strengthening my Python fundamentals for AI/ML. Built my first Command-Line Calculator in Python today. What I learned: How to use def to create functions Taking user input with input() Performing basic operations: addition, subtraction, multiplication, and division Handling errors like division by zero This small project helped me understand how functions make code cleaner and reusable. Repository: https://lnkd.in/g7Aq78ps Every small project is helping me get more comfortable with Python and problem-solving. #Python #Programming #100DaysOfCode #CodingJourney #CLI
