Anshu Kumar developed a basic arithmetic utility script for the IndustryCodeLab/learn-git-advance repository, focusing on enabling quick calculations during development and prototyping. Using Python and foundational programming skills, Anshu designed the script to add two numbers and print the result, ensuring the tool was self-contained and straightforward to review or test. The implementation followed a single-responsibility approach, making it easy to extend for additional arithmetic operations with minimal changes. While no bugs were addressed during this period, the work emphasized code quality and maintainability, providing a simple yet extensible solution for basic arithmetic needs within the project’s workflow.
