Question $1$: Write a function get$\_$total$\_$price$($cart$)$

that takes a list of dictionaries where each dictionary

represents an item in a shopping cart.

Each dictionary has two keys: "item" $($the name of the product as a string$)$

and "price" $($the price of the product as a float$).$

The function should return the total price of all items

in the cart. If the cart is empty, the function should

return $0.$
