Day-2 of learning Python | Exploring Python Shell and Module Reloading

While learning python today, I spent some time understanding how the Python shell works and how modules behave inside it. The Python shell (or REPL) is basically an interactive environment where you can run code line-by-line. It's super useful when you just want to test something quickly instead of running a full script every time. While experimenting, I tried something interesting.
