amoghsbaviskar-bit/BD-08-a-chatbot ? reverse-engineered prompt

Build me a fun Python personal assistant chatbot called BD 08 that I can run from the command line. It should understand simple commands like basic math, telling a joke, showing a motivational quote, checking the weather for a city, and opening Google, YouTube, or Spotify in the browser. I also want it to play a few goofy sound effects sometimes, like beep boop or brain sounds, and use an Excel file as a kind of simple memory for casual responses when it does not know what to say.

Make it feel playful and friendly, but still handle unknown inputs gracefully instead of crashing. For weather, leave a clear spot where I can add my own OpenWeather API key. If anything needs current docs or setup details, look them up online and make sure the app actually runs cleanly.
