Here is an exmaple to get the prices from the list. Lat say we have the following list:

items = [
    ("product1", 10),
    ("product2", 3),
    ("product3", 210),

We can use the map function as you can see below to get a list of prices.

prices = list(map(lambda item: item[1], items))

and the output is:

[10, 3, 210]
