Tell your AI that you are beginner when learning Python! I recently asked AI to generate some simple code to reverse two virtual spreadsheet columns called ‘Name’ and ‘Type’. Instead of simply suggesting code in which the column list [‘Name’, ‘Type] is replaced by [‘Type’, ‘Name’], AI suggested a complex indexing trick that looks like [::-1]. Succinct coding, to be sure, but I could not decipher it without additional prompts! In another case, my AI provided some sample code in which a variable was defined after that variable was used! The Horror! When I asked why it made such a fundamental mistake, the AI complimented me on my “good eye” for catching the error and that it did not necessarily provide code in execution order. So, if you are just learning Python, always start your session with a good prompt to set the stage such as the following: "I am a total beginner learning Python. Please follow these rules for ALL Python code you write for me: 1. Write code in execution order. 2. Break every task into small, discrete steps. 3. Use simple, obvious variable names that describe what they contain 4. Add plenty of comments explaining what it happening in plain English 5. Avoid shortcuts, clever one-liners, or condensed syntax that experienced coders use 6. If there are multiple ways to do something, choose the most readable one, not the most efficient one 7. Before showing me code, double-check it runs in the correct order from top to bottom" For more tips, consider my new book "Automate Excel with Python".

Day:1 🔥 Most developers still initialize Python variables like it’s 2015… But AI just changed the game. 👇 🧑💻 Traditional Python user_level = int(input("Enter level: ")) if user_level < 1: user_level = 1 Manual rules. Repeated validation. Static logic. 🤖 Python + AI from openai import OpenAI client = OpenAI() response = client.responses.create( model="gpt-4.1-mini", input="Suggest a default skill level for a new coding student" ) user_level = int(response.output_text.strip()) Now your variables are: ✅ Context-aware ✅ Intelligent ✅ Automatically optimized 💡 AI isn’t replacing Python — it’s upgrading how we write it. Small change → Smarter applications → Better developer productivity. Are you still initializing variables manually or letting AI assist you? 👇 #Python #AI #Developers #Programming #TechInnovation #MachineLearning #Coding

Learning Python is overrated in 2026. What’s underrated is this: BUSINESS THINKING Most people rush to learn Python, Pandas, machine learning. But they still struggle to answer one simple question: “So what?” They can build models. They can automate pipelines. But they can’t connect their work to revenue, cost, or growth. That’s the real bottleneck. Because companies don’t pay for code. They pay for decisions. The analysts who stand out today aren’t the most technical. They’re the ones who can: - Frame the right problem - Translate data into clear insights - Recommend actions with confidence Python is still useful. But it’s just a tool. If you want to be valuable in 2026, learn how the business actually works.

🐍 Python is not a language. It's a superpower. Most developers spend years jumping between tools to cover what Python handles in one. The secret? It's not just knowing Python — it's knowing which library to reach for and when: → Pandas → Data manipulation → Scikit-learn → Machine learning → TensorFlow → Deep learning → FastAPI → High-performance APIs → Django → Scalable platforms → OpenCV → Computer vision → BeautifulSoup → Web scraping → SQLAlchemy → Database access → Pygame → Game development (+ 4 more) One language. Infinite directions. Whether you're building AI models, scraping the web, or shipping web apps — Python has a library that makes you look like you've been doing it for years. 💬 What's your go-to Python library right now? Drop it in the comments — I'm building a list of community favorites. ♻️ Repost if this belongs on every developer's wall. #Python #DataScience #MachineLearning #Programming #TechCareer #Developer #AI #CodingLife

Why Python For ML? Python wasn't designed for ML. But it accidentally became the king of AI. Here's the unusual story. Day 3 of 60 → Why does EVERY ML engineer use Python? Python was created in 1991 for general programming. Nobody planned it for AI. But here's what happened:  ·      scikit-learn — made ML accessible with clean APIs ·      NumPy — made fast math possible ·      pandas — made data manipulation human-readable ·      matplotlib — made visualizations easy ·      TensorFlow + PyTorch — made deep learning reachable The community built the tools. The tools built the ecosystem. The ecosystem became impossible to ignore. Today, most of the ML engineers use Python as their primary language. It's not the fastest language. It's not the most efficient. But it's the most learnable, most readable, and most supported. For ML, that's everything. If you're just starting: Python IS the answer. #Python #MachineLearning #DataScience #Programming #60DaysOfML #AI
