1. Display the selection menu shown in Figure 1.
 Processthe user’sselection using a 𝑆𝑊𝐼𝑇𝐶𝐻 structure and ensure to account for lowercase and uppercase entries.
 If the user enters A ሺ𝑜𝑟 𝑎ሻ, invoke the function 𝑔𝑟𝑎𝑑𝑒𝑇𝑎𝑏𝑙𝑒ሺ ሻ. Once done, prompt the user again.
 If the user enters B ሺ𝑜𝑟 𝑏ሻ, invoke the function 𝑓𝑖𝑙𝑒𝑆𝑢𝑚𝑚𝑎𝑟𝑦ሺ ሻ. Once done, prompt the user again.
 If the user enters C ሺ𝑜𝑟 𝑐ሻ, terminate the program and print the message 𝑃𝑟𝑜𝑔𝑟𝑎𝑚 𝑡𝑒𝑟𝑚𝑖𝑛𝑎𝑡𝑒𝑑.
 If the user enters another value, show an error message and PROMPT the user again. The program should never
terminate unless the user selects the exit option.
2. 𝑔𝑒𝑡𝐿𝑒𝑡𝑡𝑒𝑟𝐺𝑟𝑎𝑑𝑒ሺ ሻ: accepts one parameter of type 𝑓𝑙𝑜𝑎𝑡 and returns the corresponding letter grade as follows:
Range Letter Grade
0 59 F
60 69 D
70 79 C
80 89 B
90 100 A
Other X
3. 𝑝𝑟𝑖𝑛𝑡𝐺𝑟𝑎𝑑𝑒𝑇𝑎𝑏𝑙𝑒ሺ ሻ: utilizes the function 𝑔𝑒𝑡𝐿𝑒𝑡𝑡𝑒𝑟𝐺𝑟𝑎𝑑𝑒ሺ ሻ and prints the table shown in Figure 4. You may
pick the proper column width to format and print the table.
4. 𝑓𝑖𝑙𝑒𝑆𝑢𝑚𝑚𝑎𝑟𝑦ሺ ሻ:
 Open the file “grades.dat”.
 If the file cannot be opened, display the error message “𝐸𝑟𝑟𝑜𝑟, 𝑐𝑎𝑛𝑛𝑜𝑡 𝑜𝑝𝑒𝑛 𝑓𝑖𝑙𝑒: 𝑔𝑟𝑎𝑑𝑒𝑠. 𝑑𝑎𝑡”
 Once the file is successfully opened, print the table shown in Figure 6 and use the function 𝑔𝑒𝑡𝐿𝑒𝑡𝑡𝑒𝑟𝐺𝑟𝑎𝑑𝑒ሺ ሻ.
 Compute and print the 𝑚𝑖𝑛𝑖𝑚𝑢𝑚, 𝑚𝑎𝑥𝑖𝑚𝑢𝑚, and 𝑎𝑣𝑒𝑟𝑎𝑔𝑒 of all grades in the file

You have a group of friends coming to visit for your high school reunion, and you want to take them out to eat at a local restaurant. You are not sure if any of them have dietary restrictions, but your restaurant choices are as follows:Joe’s Gourmet Burgers—Vegetarian: No, Vegan: No, Gluten-Free: No
Main Street Pizza Company—Vegetarian: Yes, Vegan: No, Gluten-Free: Yes
Corner Café—Vegetarian: Yes, Vegan: Yes, Gluten-Free: YesWrite a program that asks whether any members of your party are vegetarian, vegan, or gluten-free, to which then displays only the restaurants to which you may take the group.Here is an example of the program’s output:Is anyone in your party a vegetarian? yes
Is anyone in your party a vegan? no
Is anyone in your party gluten-free? yesHere are your restaurant choices:
Main Street Pizza Company

Python Program Description
Serendipity Booksellers has a book club that awards points to its customers based on the number of books purchased each month. The points are awarded as follows:
• If a customer purchases 0 books, he or she earns 0 points.
• If a customer purchases 1 book, he or she earns 5 points.
• If a customer purchases 2 books, he or she earns 15 points.
• If a customer purchases 3 books, he or she earns 20 points.
• If a customer purchases 4 or more books, he or she earns 30 points.
Design a program that asks the user to enter the number of books that he or she has purchased this month and displays the number of points awarded.
Step 1: Create a flowchart for this program which includes:
• A main module which controls the flow
• A getData module which asks the user how many books were purchased
• A getPoints earned module which gets the points earned based on the number of books
• A displayPoints module which outputs the number of books purchased and the number of points earned.
Step 2: Use the flowchart from step 1 as a guide to writing your program in Python.

In this exercise your task is to write code that will produce a table of weights in both kilograms (kg) and pounds (lb). You should use the following conversion/( 1 kg = 2.20462 lb /)You are given a list of weights (as strings) in either kilograms or pounds, e.g.,10.0 kg
5.1 kg
52 lb
20 kg
where a space separates the weight value from the units.Your code should output a table of weights containing both kilograms and pounds. To help you we have written a function called print_row to print each row of the table. You should call this function when you wish to output a row in the table as it will format the row in the way we expect.For example, the output for the input given above should be:kg lb
10.0 22.0
5.1 11.2
23.6 52.0
20.0 44.1

In a Vigenere cipher a plaintext message is encrypted by adding letters from a secret key (modulo 26). For example, A + X is X, B + X is Y, C + X is Z, D + X is A, etc.

Decryption is achieved by subtracting the same sequence of letters from the ciphertext. If the message is longer than the key then the letters of the key are simply repeated.

For example, given the key KEY and the message HELLO WORLD we would generate ciphertext as follows:

HELLO WORLD
KEYKE YKEYK

You will write two functions in this challenge. First write a function called rec_dig_sum that takes in an integer and returns the recursive digit sum of that number.Examples of recursive digit sums:
101 => 1+0+1 = 2
191 => 1+9+1 = 11 => 1+1 = 2
5697 => 5+6+9+7 = 27 => 2+7 = 9Then use that function within another function called distr_of_rec_digit_sums, that returns a dictionary where the keys are recursive digit sums, and the values are the counts of those digit sums occurring between a low and high (inclusive) range of input numbers. Assume low and high are positive integers where high is greater than low, and neither low nor high are negative. Your function should return a dictionary, not just print it.You can test your code as many times as you need. Your code will save if you need to come back later.
Question 2Write a function called sigmoid that implements the sigmoid logistic function, as it is shown in this article.For the value of Euler’s number e use 2.71828.Your function should return a number, not just print that number.
