And what is wrong with
cost_for_all_pizzas = 0
for food in menu:
match food:
case {"type": "pizza", "price": price}:
cost_for_all_pizzas += price
Seriously, people are just getting used to match statements (I had to
look the syntax up for the above) so IMO it's a bit early to be trying
to cram them into dubious one-liners.
