August 2025 Monthly Summary: Delivered a new Sum Calculator Script in the Paskod121/C2P-Python-Essentiel repository, enabling quick, validated arithmetic tasks for the team. The Sum Calculator Script (sommeAuto.py) prompts the user for a number n > 1 and computes the sum from 1 to n with input validation, reducing manual calculation errors and speeding up lightweight numerical checks. No major bugs fixed this month; focus was on feature delivery and code quality. The addition demonstrates solid Python scripting, CLI UX, and clean commit practices, laying groundwork for broader utility scripts and reuse across projects.
