Question
Python Code:
Use def functions.
Please upload the code. Thank you.
Stop when and only when the user has exactly five courses.
Whenever the user must add courses, accept a comma-separated list of courses, and add each of them.
Before adding the course, remove any whitespace around its name, and correct its capitalization.
Whenever the user must drop courses, accept a comma-separated list of courses, and delete each of them.
Treat the names the same way and the comparisons will be easy.
You need to check for, and ignore, them trying to drop courses they aren't taking!

- Can you please fix the code ? see picture for error thank youarrow_forwardPlease Program in python and leave comments to help explain here is the google drive with the Test.xlsm file: https://drive.google.com/drive/folders/16utzb5_h7yMCN8_13E_JqasfcpykZOYr?usp=sharing The objective is to create a code in Python that can extract the columns highlighted in blue and output them to a .txt file. The code should be able to generate the text file with the columns that are highlighted in blue and store them on a seperate folder. Below shows how the Test.xlsm file looks like as well as how the text file should look like when the code extracts and outputs it. The attached images is how we want to format the text file when/after extracting the columns highlighted in blue. The code should name the output text file according to the sheet name " Correct-L.txt " and its header should contain " Band Group Number Time " just so we know where it begins or when the next column is.arrow_forwardWhich of the following statements DOES NOT delete the last value in the list lst? a) 1st.pop( b) 1st.remove(-1) c) 1st = lst[:-1] d) 1st.pop(len(lst)-1)arrow_forward
- You are working with a team creating a grocery shopping app. The app keeps the information of the items to buy in the list grocery list, and the items that were purchased in purchased list. You need to create a function that returns the items that were purchased, but that were not in the grocery list. For example, if the grocery list is milk, eggs, bacon, and flour; and we purchased milk, chocolate, and muffins, the function should return a list with chocolate and muffins. Drag and drop the expressions needed to implement the required function. def get_extra_items(grocery_list, purchased_list): list3 [] for i in range( ) : if not in list3.append( return list3 len(grocery_list) grocery_list grocery_list[i] purchased_list[i] purchased_list len(purchased_list)arrow_forwardIn C++ Programming Language & Give me the answer in Visual Studio Please!!!arrow_forwardhelp with python code import time timeStamp = time.ctime()print(timeStamp)forum_list = [ {'date':'10-01-2022', 'name':'Student1', 'comment':'Very helpful'}, {'date': '10-01-2022', 'name': 'Student2', 'comment': 'Very good'} ] menu = """ Forum Comments 0: Exit 1: Display Comments 2: Add Comment """ done = False while not done: print(menu) selection = input('Please make a selection: ') if selection == "0": done = True print('Exiting now, thank you for participating') if selection == "1": for d in forum_list: print(d['date'], end='') print(' ', end='') print(d['name']) print(d['comment']) if selection == "2": comment = {} comment['date'] = input('Please enter date: ') comment['name'] = input('Please enter name: ') comment['comment'] = input('Please enter comment: ') forum_list.append(comment) # what's inside the data.txt file #Date Name…arrow_forward
- Python question please include all steps and screenshot of code. Also please provide a docstring, and comments throughout the code, and test the given examples below. Thanks. Write a function called honorRoll(). Its only input parameter is a list that contains listsconsisting of a name followed by a series of grades (integers). All grades will be in therange 0-100. All students will have at least one grade, but not all students will have thesame number of grades. Your function should return a list of students whose averagegrade is above 92.0.>>> honorRoll([['Alice', 95, 92, 98], ['Carlos', 85, 87, 95, 91], ['Betty', 81, 74, 89]])['Alice']>>> honorRoll([['Alice', 92, 92, 92], ['Bob', 81, 46]])[]arrow_forwardIn the space provided below, write a C++ code that asks a user to enter the names of their favorite albums along with the year each album was released one at a time. As the user enters the data, the program inserts each name into a linked list such that the list in ascending order based on the release year. Your program also allows the user to delete any of the albums from the list. The list maintained will always be in sorted order and will be displayed as such whenever the user is finished updating the list. You must use classes/objects, linked lists, and pointers. Using the embed icon shown above, include copies of your screenshots demoing the execution of your program for various input patterns.arrow_forwardCase Problems - 1- In Chapter 8, you modified the EventDemo program for Carly’s Catering to accept and display data for an array of three Event objects. Now, modify the program to use an array of eight Event objects. Prompt the user to choose an option to sort Events in ascending order by event number, number of guests, or event type. Display the sorted list, and continue to prompt the user for sorting options until the user enters a sentinel value. Save the file as EventDemo.java.arrow_forward
- python help, please show all steps and include comments Write a function largerLst() that takes a list of numbers (i.e., int or float values) as a parameter and returns a new list constructed out of it. The list returned has all the values in the parameter list that are larger than the element immediately to their right, that is, larger than their right neighbor. If the parameter list is empty or there are no values larger than their right neighbor, then the function returns an empty list. Note that the last element in the list will never be included in the list returned since it does not have a right neighbor. The function should not change the parameter list in any way. Note that a correct solution to this problem must use an indexed loop That is, one that makes a call to the range() function to generate indices into the list which are used to solve the problem (Review lecture notes 8-1). A solution that does not use an indexed loop will not be accepted. Note in particular that you…arrow_forward| Which data structure to use? Suppose you need to store a list of elements, if the number of elements in the program is fixed, what data structure should you use? (array, ArrayList, or LinkedList) If you have to add or delete the elements at the beginning of a list, should you use ArrayList or LinkedList? If most of operations on a list involve retrieving an element at a given index, should you use ArrayList or LinkedList?arrow_forward3. Which among the following shows a valid use of the Direction enumeration as a parameter to the moveCharacter function? Select al that apply. enum Direction { case north, south, west, east}func moveCharacter(x: Int, y: Int, facing: Direction) {// code here} moveCharacter(x: 0, y: 0, facing: .southwest) moveCharacter(x: 0, y: 0, facing: Direction.north) moveCharacter(x: 0, y: 0, facing: .south) moveCharacter(x: 0, y: 0, facing: Direction.northeast)arrow_forward
