Welcome, brave Python knight! 🛡️
Your quest today is to explore the Holy Grail Inventory, a legendary collection of absurdly powerful (and occasionally ridiculous) items from the world of Monty Python and the Holy Grail.
Hidden within this program is a list of lists — each item contains multiple pieces of information packed together like a medieval knapsack. Your job is to unpack those values correctly and use them to display information, make selections, and avoid catastrophic program crashes (no one likes a surprise Holy Hand Grenade).
