Python Habits for Professionals: Separating Beginners from Experts

4 Python Habits That Separate Beginners from Professional Developers After reviewing code from 100+ students and building production systems at FLM, I've noticed patterns that make or break Python developers: 1. Beginners write scripts. Professionals write modules. ❌ One 500-line script doing everything ✅ Organized modules with clear responsibilities 2. Beginners ignore error handling. Professionals plan for failure. ❌ result = data[0] (crashes if empty) ✅ result = data[0] if data else default_value 3. Beginners hardcode values. Professionals use config files. ❌ API_KEY = "abc123" scattered everywhere ✅ Environment variables + config management 4. Beginners comment what code does. Professionals comment WHY. ❌ # Loop through items ✅ # Calculate weighted average to handle outliers These aren't advanced concepts. They're professional habits that make your code maintainable, scalable, and production-ready. Want structured Python learning from basics to advanced?
