Flask API Request Lifecycle in 5 Steps

Your app crashed. A user got a blank screen. No error message. No recovery. That's what happens when you skip exception handling. 😬 Here's the thing — errors WILL happen in every app: → User types text where a number is expected → API goes down mid-request → Division by zero in your logic → File doesn't exist at the path you assumed The question isn't IF errors happen. It's whether your app handles them gracefully. Python's try/except block is your safety net: try: risky_code() except ValueError: handle_it() except ZeroDivisionError: handle_it_differently() finally: always_runs() I use this in every single Flask route I build — especially when calling external APIs where anything can go wrong. Clean error handling = happy users + easier debugging.

Day 134 of My Data Science Journey: Today I studied Streamlit Web App Development & Deployment Here’s what I learned: 🔹 How to deploy Streamlit apps on free servers 🔹 Making apps accessible to the public 🌍 🔹 Preparing projects for real-world use 🔹 Understanding deployment challenges and how to solve them Now it’s not just about building apps, but also sharing them with the world 🔥 💡 Key Learning: If you don’t deploy your project, it stays limited to you. #Day134 #Streamlit #WebDevelopment #DataScience #Python #Learning #BuildInPublic

Here's a clear visual breakdown of a typical Django project folder structure — perfect for beginners or anyone setting up a new project. Key highlights: • Root project folder contains global settings, URLs, WSGI/ASGI entry points • Each app (App-1, App-2…) has its own models, views, templates, migrations, etc. • Project-level templates/ and static/ folders for shared assets across all apps • App-specific templates live inside app/templates/app-name/ • manage.py sits at the root — your best friend for migrations, runserver, shell, etc. Keeping this structure clean from day one saves so much time when the project grows. #Django #Python #WebDevelopment #BackendDevelopment #Programming #SoftwareEngineering #CodeQuality

As part of my data science journey, I developed this interactive app using the Open-Meteo API. It fetches live weather data and displays current conditions along with a 24-hour interactive forecast. 🔗 Live App: https://lnkd.in/e8Y5hHZx I'd love for you to search your city and share your feedback! 👇 #Python #DataScience #Streamlit #DataVisualization #API

I made this for my learners. Now I’m sharing it for free. Before you deploy your first LLM app, check your prompts, guardrails, edge cases, hallucination risk, vector DB setup, API security, rate limits, logging, and more. A strong demo is easy. A reliable production app is different. This 10-step checklist will help you avoid common mistakes and build smarter from day one. Download it, save it, and use it before your next deployment. #LLM #GenerativeAI #AIDeployment #FreeResource #Python #LangChain

Built an app in 30 minutes with AI. Stack was React, Python, PostgreSQL. Had AI generate the API schema, CRUD endpoints, and UI components. Connected everything with Axios. Result: Working app in under 30 minutes. AI didn't replace development. It handled the repetitive stuff faster. Still had to think through system design, debug issues, and model the data properly. Developers are becoming system orchestrators instead of just code writers. Would you use AI for production apps?

🚀 From Basic Flask Apps to Real-World Features While learning Flask, I explored two important concepts that make applications more practical: 🍪 Cookies – Help store user data in the browser and improve user experience 📂 File Upload – Allows users to upload images, documents, and more 💡 What I learned: Cookies are useful for tracking users but should be handled carefully File uploads bring real functionality to web apps (like profile pictures, docs, etc.) This step really made me feel like I’m moving from just learning → building real applications 💻✨ Next goal: 🔐 Implementing secure authentication #Flask #Python #WebDevelopment #Backend #LearningJourney #Coding

Inspired by an excellent talk at Python Floripa (thanks to Rodrigo Vieira (https://lnkd.in/dbyyWkkQ)), I have written an article titled "ORM N+1 handlers to streamline queries." This piece addresses the challenges faced by Prisma/Node.js developers dealing with performance bottlenecks. You can read it here: https://lnkd.in/dWTG2RXg. I appreciate events like Python Floripa that provide opportunities for real-world solutions. I would love to hear your N+1 optimization tricks. #PythonFloripa #ORM #N1Queries #BackendDev #Prisma

I wasted 𝗱𝗮𝘆𝘀 before understanding this in GUI development… I thought building a simple slideshow app would be easy -- just load images and switch them, right? Wrong. The moment I started, everything broke: • Images didn’t fit the window • The UI froze during transitions • Timing felt completely off That’s when I realized -- GUI apps don’t work like normal scripts. So I decided to build one properly 👇 🚀 𝗜𝗺𝗮𝗴𝗲 𝗦𝗹𝗶𝗱𝗲𝘀𝗵𝗼𝘄 𝗔𝗽𝗽 (𝗣𝘆𝘁𝗵𝗼𝗻 + 𝗧𝗸𝗶𝗻𝘁𝗲𝗿 + 𝗣𝗜𝗟) What it actually does: • Smooth automatic image transitions • Proper resizing to fit the UI • No freezing during updates • Simple interactive controls The biggest thing I learned? GUI apps are 𝗲𝘃𝗲𝗻𝘁-𝗱𝗿𝗶𝘃𝗲𝗻 -- 𝗻𝗼𝘁 𝗹𝗶𝗻𝗲𝗮𝗿 𝗹𝗶𝗸𝗲 𝘀𝗰𝗿𝗶𝗽𝘁𝘀. That shift in thinking changes everything. 🔗 GitHub: https://lnkd.in/gBZbuhzQ What’s a “simple” project that turned out to be harder than you expected? #Python #SoftwareDevelopment #Programming #PythonProjects #Tkinter #BuildInPublic #CodingJourney
