Using Python, write code that opens the file “groceries.txt”. This file contains a shopping list. You want to read this list from the file and store each grocery item in a list of strings. Each item in this list should be one of the grocery items. None of the strings in the list should have newline breaks or other special characters. Sort the list of grocery items in alphabetical order. The sort should ignore case, though. Regardless of the fact that the grocery items are listed in mixed case, they should be sorted in this order: Apples, Bananas, Cheddar Cheese, Grapefruit, Milk, Zucchini Add code that opens the file “prices.txt”. This file contains a list of prices for various items. You want to read this list and use it to create a dictionary, where the keys are the items and their corresponding values the prices. Hints. The files lesson presents three ways to process files. The variant I used when I wrote this program for myself is: for line in fileObject : To process each line, you will need to strip the extraneous whitespace, then split the line into two strings. You can use the split(”,”) method to do this. Splitting the line will give you a list with two strings in it. The first element of this list is your key. The second element of the list is the price. Open the file “shopping.txt” for writing (not appending). This file doesn’t have to exist on your computer–Python will create the file if it doesn’t exist. Your objective is to print a shopping list to this file. The shopping list should list all of the groceries in alphabetical order. They should be numbered (starting with 1–not 0). Each line should have the number, a period, a space, then the capitalized grocery item. At the end of the list you should print the total bill, computed by looking up the price of each item and tallying the prices. The price should begin with a dollar sign and consist of dollars and cents. There should not be any fractions of a penny (i.e. you should not have more than two decimal digits). Sample output is provided below. 1. Apples 2. Bananas 3. Cheddar cheese 4. Grapefruit 5. Milk 6. Zucchini Total Bill: $12.04

Prob 2. Suppose $\mathbb{F} = \mathbb{R}$ or $\mathbb{F} = \mathbb{C}$ and let $U = \{(x, y, x+y, -y, -x) \in \mathbb{F}^5 : x, y \in \mathbb{F}\}.$ Find three subspaces $W_1, W_2, W_3$ of $\mathbb{F}^5$, none of which equals $\{0\}$, such that $\mathbb{F}^5 = U \oplus W_1 \oplus W_2 \oplus W_3$.
