Using phyton code: First, ask the user the following three questions and store the answers in a nested list. What is your name? What is your quest? What is your favorite color? Store at least 6 sets of responses. Example nested list: [ ['Sir Robin' , 'to find the Holy Grail' , 'red'] , ['Matt' , 'to travel the world' , 'blue'], etc...] Second, sort the list alphabetically by color and print out the results: Sample output:

Lab Exercise #6: Product Price List In this activity, you are to create a program that will maintain a list of products and their prices. The program is a menu- driven program that has choices for adding a new product and its price, listing all products with corresponding prices. updating the price of a product, and removing a product. A sample execution is given below: [U]pdate | [L]ist | [E]xit Menu: [A]dd| [R]emove Option: A Product: Notebook Price (Php): 15.00 Option: A Product: Pen Price (Php): 10.00 Option: A Product: notebook *The product already exists* Option: U Product: notebook Price (Php): 18.20 Option: A Product: Pencil Price (Php): 8.50 Option: L NOTEBOOK PEN PENCIL Option: R Product: Pen 18.20 10.00 8.50 Option: R Product: PEN *The product does not exist* When adding an item, the product name and its price will be given. Product names are unique, case-insensitive, and with leading and trailing spaces removed. Therefore, adding the same product more than once is not…

The mean of a list of numbers is its arithmetic average. The median of a list is its middle value when the values are placed in order. For example, if an ordered list contains 1, 2, 3, 4, 5, 6, 10, 11, and 12, then the mean is 6, and their median is 5. Write an application that allows you to enter nine integers and displays the values, their mean, and their median.
A spell checker in a word processing program makes suggestions when it finds a word not in the dictionary. To determine what words to suggest, it tries to find similar words. One measure of word similarity is the Levenshtein distance, which measures the number of substitutions, additions, or deletions that are required to change one word into another. For example, the words spit and spot are a distance of 1 apart; changing spit to spot requires one substitution (i for o). Likewise, spit is distance 1 from pit since the change requires one deletion (the s). The word spite is also distance 1 from spit since it requires one addition (the e). The word soot is distance 2 from spit since two substitutions would be required. a. Create a graph using words as vertices, and edges connecting words with a Levenshtein distance of 1. Use the misspelled word “moke” as the center, and try to find at least 10 connected dictionary words. How might a spell checker use this graph? b. Improve the method…
The for construct refers to a loop that processes a list of items. Therefore, it continues to operate as long as there are items to process. Is this a true or false statement?
This problem looks at your proficiency using a while loop for a menu driven interface and your proficiency with the list data structure. Create a menu with that gives the user three choices: Grade Book O: Exit 1: Display a sorted list of grades 2: Add a grade to the list Create an empty list at the start of the program. Display the menu at the start of the while loop and then prompt the user for a selection. For # 1, you do not have to get fancy with your display. Simply displaying the list in a print statement is good enough. Remember to sort the list before displaying it. For #2, prompt the user to enter a grade and then add it to the list. For #0, exit the while loop and display, "Good bye!". The images below show what your dialog should look like. The list starts off empty. The user then adds three grades to the list. The next time the list is displayed, the three grades are shown in ascending order. Lastly, the user exits the program. Note that user input is highlighted in green.…
Loop through the animalList created in a previous question and print the total time taken and total time given for each animal. Example output: Zirly the Zebra - Time taken for all behaviors: 890 minutes of 1000 Henry the Hawk - Time taken for all behaviors: 350 minues of 1000 Choose one of the following from the above choices (A, B, C or D within the code):// Assume the following variables exist: Behavior[] someBehaviors = // Omitted for brevity Animal zirly = Animal("Zirly the Zebra", 812.3, someBehaviors); Animal henry = Animal("Henry the Hawk", 35.5, someBehaviors); Animal[] animalList = new Animal[]{ zirly, henry }; // --------------------------- // A for(int i = animalList.length; i < animalList.length; i++) { Animal tempAnimal = animalList[i]; int timeTakenSum = 0; int timeGivenSum = 0; for(j = 0; j < tempAnimal.getBehaviorList().length; j++) { Behavior tempBehavior = tempAnimal.getBehaviorList()[j]; timeTakenSum +=…
In python, The function count_contains_x takes a list of strings (wordList) and returns the count of how many strings in the list contain at least one upper- or lower-case 'x'. Hint: Use the accumulator pattern to accumulate the count. Hint: You might want to use the string method count. For example: Test Result strlist = ["xerox", "OXEN", "whiffleball", "XOXOX"] print(count_contains_x(strlist)) 3 fish = ["angel", "gold", "cat", "puffer", "damsel"] print(count_contains_x(fish)) 0 strlist = ["X", "x"] print(count_contains_x(strlist)) 2 list_of_one_x = ["x"] print(count_contains_x(list_of_one_x)) 1
Scylla or Charybdis? def scylla_or_charybdis(moves, n): This problem was inspired by the article "A Magical Answer to the 80-Year-Old Puzzle" in Quanta Magazine. Thanks to your recent cunning stunts, your nemesis in life is trapped inside a devious game where, for a refreshing change from the usual way of things, you get to be the Final Boss. (Everyone is the hero in their own story until they become a villain in somebody else's, after all.) This final level is a one-dimensional video game platform that reaches n-1 steps from its center to both directions. At each end of this platform exactly n steps away from the center, your two lethal friends Scylla and Charybdis are licking their lips in anticipation of a tasty morsel. Your nemesis starts at the center of this platform. To start this deadly combat of wits, she must immediately commit to her entire sequence of future moves, given to this function as a string of characters '+' (“� just a step to the ri-i-i-i-ight � ”) and '-' (move…
