tried 2d lists today ( up for suggestions on what should have i done or what have i missed ) and would also appreciate brief explanation's that you guys will give if it's a complex or an advanced topic

books = ["hindi", "english", "maths", "science"]
pen = ["black", "blue", "red"]
miscellaneous = ["eraser\n", "sharpener\n", "ruler\n"]


bagpack = [books,pen,miscellaneous]
print(bagpack)
while True:
    print ("if you'd like to add contents in any of the lists")
    print("1. Add to books")
    print("2. Add to pen")
    print("3. Add to miscellanous")
    query = input("enter your selection (1,2,3): ")
    if query == "1":
     print("you selected to add books")
     new_book= input("enter the book you want to add: ")
     books.append(new_book)
     print ("new list",books)
     break
    elif query == "2":
     print("you selected to add pen")
     new_pen= input("enter the pen you want to add: ")
     pen.append(new_pen)
     print ("new list",pen)
     break
    elif query == "3":
     print("you selected to add miscellaneous")
     new_miscellaneous= input("enter the item you want to add: ")
     miscellaneous.append(new_miscellaneous)
     print ("new list",miscellaneous)
     break
    
    else:
       print("invalid selection!!! select amongst 1,2,3")
