One Dockerfile, Two Stages: A 50% Size Reduction Story

On day 19 of my learning journey, I made significant progress by creating a README.md summarizing my week-two content and successfully merging it into the main branch on GitHub. I also updated my local repository and the python-concepts README.md with new topics I've learned. This week, I initiated a new branch for week-three and set daily milestones to track my progress. This structured approach not only helps me stay organized but also enhances my learning experience, making it easier to reflect on my growth.

Docker is revolutionizing how we deploy websites by allowing developers to package their applications in containers that run consistently across different environments.
