🧑💻 Building My Own CLI using Python's cmd.Cmd Module I explored some-useful models in python then i came across Python's cmd.Cmd which is used to create command line interfaces. Since then I have been working on a custom Python command-line shell, and it turned into a great learning experience beyond just syntax and development cycle. - It has given me experiencing First-hand creator perspective 🤓: - Some of the concepts i have implemented in my current learning : 🔹 Built a custom shell with commands like: create_path → register app launchers run <alias> → launch apps via aliases (Windows .lnk support) 🔹 Used shlex.split() for proper shell-style argument parsing → supports quoted paths with spaces, just like a real terminal 🔹 Implemented persistent state using JSON → launchers survive across sessions (launchers.json) 🔹 Designed all-or-nothing validation → if any path is invalid, nothing is saved (transaction-style logic) 🔹 Learned key design principles: → Load-once, save-on-change → Graceful handling of first-run scenarios (no config file) → Extend framework behavior using super() instead of rewriting it This project really reinforced the difference between: 👉 code that works once 👉 code that behaves correctly in real-world scenarios Always building, always learning. 💪 If you enjoy Python internals, CLI tools, or system-level programming, let’s connect.

Let us see how to download Python and set it up on our local system. First, we use the command: where python This command tells us the path where Python is located and where the software is installed on the Windows machine. If you want to know the Python version installed on your system, use: python --version Next, we need to choose an editor, and we will use PyCharm. Download PyCharm Community Edition for Windows 11. There are two versions available: 1. A paid (Professional) version 2. A Community (free) version You can work with the Community edition without paying, which is more than sufficient for learning and automation work. Download PyCharm from: https://lnkd.in/gJyRZfEb While setting up PyCharm: 1. Select Custom Environment 2. Choose the Existing Interpreter radio button 3. Provide the path to your local Python installation Example path: C:\Users\Sunita\AppData\Local\Microsoft\WindowsApps From the Command Prompt: Microsoft Windows [Version 10.0.26200.7462] (c) Microsoft Corporation. All rights reserved. C:\Users\Sunita>where python C:\Python313\python.exe C:\Users\Sunita\AppData\Local\Microsoft\WindowsApps\python.exe C:\Users\Sunita> To verify the version: python --version Python 3.13.3 We have successfully installed Python, and with these two commands, we can verify whether Python is correctly reflected on the system. One very important point to focus on here: By default, PyCharm also provides its own Python environment. Even if you do not install Python on your system, the IDE creates a Python environment for each project. However, my personal recommendation is not to depend on the environment provided by the IDE. Instead: Install Python on your local system Use that local Python path inside PyCharm by selecting Custom Environment This ensures better control, consistency, and real-world readiness for automation, testing frameworks, and CI/CD setups. #Python #PythonInstallation #PyCharm #AutomationTesting #SDET #SoftwareTesting #LearningJourney #Windows11 #TestAutomation #Playwright #PyTest #CareerGrowth #ContinuousLearning

Just recently, I built a Laravel setup automation tool using Python, here's the link ( https://lnkd.in/dSMrQQTU ) . It was a fun little project, full of lessons and small discoveries along the way. One of the things it really taught me was how opinionated automated tools work. Tools like Herd, ldjango, and others are designed to help developers set up projects faster and with less friction. You basically activate the tool, tell it what you want, and it just spins everything up for you. No stress. Building my own tool gave me a better mental picture of what might be going on under the hood in tools like Herd. Now, this is just a thought I’ve had for a few days — it might be completely wrong or slightly accurate — but I figured I’d share it anyway. Laravel setup with Herd feels much faster than using the CLI directly. Normally, Laravel has to be downloaded, files created, and dependencies resolved, and all that takes time. So I started wondering: what if Herd already has those files somewhere? What if it’s just copying them into your project directory instead of downloading everything from scratch? Maybe Laravel already lives in some kind of environment or container, and when you create a new project, it’s more of a copy-and-setup process rather than a full install. That could explain the speed. Maybe Herd already has PHP, Laravel, and everything else ready to go in the background. Again, this is just a theory — something I’ve been thinking about lately. I’m planning to dig deeper and see how close (or far off) I am. #laravel #python #softwaredevelopment

Using Python to Automate Developer Workflows Over the last few weeks, I’ve been learning Laravel and working to improve my skills. One thing kept slowing me down though—the setup process. It felt long and repetitive, so I decided to do something about it. I built a small Laravel automation tool using Python to streamline the setup process and, at the same time, learn more about Python automation. What I set out to do: ☑ Automate Laravel project creation ☑ Initialize Git repositories ☑ Learn how automation works in Python ☑ Understand Python subprocesses What I achieved: ✔Folder creation using tkinter ✔Automated Laravel setup via Composer ✔Git initialization and optional remote push ✔Hands-on experience with Python subprocesses This project was genuinely fun and very educational. One thing that surprised me most was that I didn’t need any external libraries—everything was built using Python’s standard library. A great reminder that automation doesn’t always require heavy tools—sometimes the basics are more than enough. I think this is awesome, so anyone can just go to the project and get it running just as long as they have python installed. To check out the project: https://lnkd.in/eaKKC9Ta What are you currently automating? #python #laravel #automation #softwaredevelopment Below is some snippets of my project code

Filo - Python Project: Folder Organizer (CLI Tool) Is your download folder flooded with files? Here's the solution! I built a Python-based command-line tool that automatically organizes files in a directory by categorizing them into folders based on their file extensions. This script allows users to provide a directory path (for example, the Downloads folder), scans all files inside it, and neatly sorts them into folders such as Music, Videos, Images, Documents, Archives, Code, and Applications. If a required folder doesn’t exist, it is created automatically. This project was built as both a practical automation utility and a hands-on learning exercise to strengthen my understanding of Python file system operations. Key Features Automatically organizes files by extension Creates destination folders when they don’t exist Supports common file types (media, documents, archives, code, apps) Simple and user-friendly CLI interaction Lightweight and dependency-free How It Works User provides the directory path to organize Script scans all files in the directory Files are grouped using Python dictionaries Folders are created based on extension mapping Files are moved into their respective folders How to Run python filo.py Then enter the absolute path of the directory you want to organize (example): /home/user/Downloads/.. Github: https://lnkd.in/gi9aWAw3 This project helped me improve my skills in automation, file handling, and writing clean, practical Python scripts. #Python #PythonProjects #Automation #CLI #FileManagement #SoftwareDevelopment #LearningByDoing #Coding #OpenSource #DeveloperJourney #TechProjects #Programming #Linux #Productivity

How Python Actually Runs? Ever wondered what happens the moment you hit "Run"? Python doesn't just read your code like a book; it goes through a fascinating two-step process to turn your logic into action. Here is the simple breakdown: • The Compilation Phase Before your code executes, Python "compiles" it. No, it doesn't turn it into a Windows .exe file. It transforms your source code into Bytecode. - Think of it as: Translating a complex recipe into a simplified checklist that only a chef understands. - The Result: Those .pyc files you often see in __pycache__ folders. • The Interpretation Phase This is where the Python Virtual Machine (PVM) takes over. It reads the Bytecode line-by-line and executes it on your computer. - Think of it as: The chef following that checklist to actually cook the meal. - The Benefit: This is why Python is "cross-platform" the same Bytecode can run on Windows, Mac, or Linux as long as the PVM is there. 💡 Why should you care? Understanding this model helps you realize why Python is so flexible. It’s an Interpreted language, meaning it’s optimized for developer speed and ease of use, even if it trades off a little bit of raw execution power. #Python #DataEngineering #DataScience
