Inventory value

An inventory maps each item to a dictionary with its price and qty: {"pen": {"price": 1.5, "qty": 4}}.

Write inventory_value(inventory) returning the total value (price × quantity, summed), rounded to 2 decimals.

def inventory_value(inventory):
    total = 0
    for item in inventory:
        total += item["price"] * item["qty"]
    return round(total, 2)

Run adds print(inventory_value({"pen": {"price": 1.5, "qty": 4}})) after your code, to try it.
