A café's till lets staff type the item name, so the same drink shows up as "Green Tea", " mint TEA" and "tea". The owner wants the takings for every item that has a certain word in its name.
Task: write keyword_takings(sales, keyword).
sales is a list of dictionaries, each with item (text) and price (a number).keyword is always given in lowercase, like "tea".keyword anywhere, ignoring capitals and spaces at the ends. Part of a longer word counts too, so "Teacake" contains "tea".price of the items that count, rounded to 2 decimal places. If none count, return 0.0.There is always at least one sale.
