Day 3/30 – Python Challenge 🐍 Today I built: File Search Tool 🔍 🔹 What it does: Searches for files in the system by name and returns their location instantly. 🔹 What I learned: Working with file systems using os module Traversing directories using os.walk() Handling user input and search logic 🔹 Challenge: Optimizing search for large directories and handling different file paths 👉 GitHub link: https://lnkd.in/dj_FEm5j Building real-world tools step by step 🚀 #Python #CodingChallenge #LearnInPublic #100DaysOfCode #Automation #DeveloperJourney

Architecting scalable social feeds and mastering JWT authentication. Reality: Fighting with a curl command at 9:56 PM because of a missing field or a malformed URL. Development isn't just about the big wins; it's about the 45 minutes you spend debugging a "Malformed input" error only to realize it was a syntax slip. Onward to the next fix! #SoftwareEngineering #BackendDev #Python #CodingLife #Debugging

A lot of developers try to make their code “clean” by following a checklist. Small classes. Short functions. Everything abstracted behind services and containers. The result often looks tidy, but changing the behaviour of the program is still hard. The real logic is scattered across too many layers. In today’s video, I refactor a small Python program and show why optimizing for smallness often leads to worse designs. What actually matters is cohesion: grouping things that change together and making the workflow of the program easy to understand. 👉 Watch the full video here: https://lnkd.in/g2txBqi6. #python #softwaredesign #cleancode #refactoring #arjancodes

Hot take: managing Python projects doesn't have to be complicated. 🔥 I switched to uv a while back and haven't looked back since. Here's what my workflow looks like now: → uv init my-project (project scaffolded in seconds) → uv add requests pandas (dependencies locked automatically) → uv run main.py (runs in the right environment, every time) No more "it works on my machine." No more version conflicts. No more three separate tools open at once. uv handles everything — and it does it fast. We're talking 10–100x faster than traditional pip installs. Are you already using uv? Drop a comment — I'd love to hear how it's changed your workflow! 👇 https://docs.astral.sh/uv/ #Python #uv #CleanCode #Productivity #OpenSource

If your code is starting to look like spaghetti, it’s time to master Modules and Packages. This infographic is a perfect "cheat sheet" for: ✅ Modules vs. Packages – How to structure your files. ✅ Imports – The right way to bring in code. ✅ Virtual Environments – Keeping your projects clean and isolated. Pro-tip: Never skip the virtual environment. Your future self will thank you when you avoid version conflicts! 💡 What’s one Python tip you wish you knew when you started? 👇 #Python #Coding #SoftwareEngineering #TechTips

When was my friends were playing #FLAMES 😁😉, repeatedly doing the same calculations again and again. At that movement, I got an idea nowadays everything is automated, so why not automate FLAMES too? so, I came up with a python solution 🤔😎. Take a look 🤫🫣🫨 #python #problemsolving #crasy #pythonprogramming #fun #automation #play

🚨 STOP: You’re nesting your code too deep. If your Python/JS logic looks like a staircase, you're making it 10x harder to debug. The Shortcut: The "Guard Clause" 🛡️ Instead of a giant if block, check for errors and return early. ❌ The Mess: if user: if user.is_active: # 10 lines of logic here... ✅ The Clean Way: if not user or not user.is_active: return # Logic stays at the top level! It works in every language. Keep the "Happy Path" flat. Do you "Return Early" or are you a Nested Nestler? 👇 #CleanCode #Python #JS #SoftwareEngineering

I recently built a tool called ELI5 Simplifier to make technical jargon easier to understand. The application takes complex text or images and simplifies them to your chosen level using a React, FastAPI, and Hugging Face stack. You can try the live version here: https://lnkd.in/gigkk_GX #ai #webdevelopment #python #reactjs #fastapi #huggingface #fullstack

Quick Refactor Example: Instead of the long if block, you could do this: def calculate(self): avg = sum(self.scores) / len(self.scores) # Define thresholds and grades in descending order grades = [(90, 'O'), (80, 'E'), (70, 'A'), (55, 'P'), (40, 'D')] for threshold, letter in grades: if avg >= threshold: return letter return 'T' # Default for anything below 40 It’s the exact same logic, just a bit more "DRY" (Don't Repeat Yourself). #Python #CodingChallenge #100DaysOfCode #SoftwareDevelopment #LearningToCode
