Program Specification
For this assignment you will write a program to help people record the events of their day by supplying prompts and then saving their responses along with the question and the date to a file.
Functional Requirements
This program must contain the following features:
Write a new entry - Show the user a random prompt (from a list that you create), and save their response, the prompt, and the date as an Entry.
Display the journal - Iterate through all entries in the journal and display them to the screen.
Save the journal to a file - Prompt the user for a filename and then save the current journal (the complete list of entries) to that file location.
Load the journal from a file - Prompt the user for a filename and then load the journal (a complete list of entries) from that file. This should replace any entries currently stored the journal.
Provide a menu that allows the user choose these options
Your list of prompts must contain at least five different prompts.…

Please eneter a state: Georgia
Georgia has been added to the list
Enter another name(Y/N): Y
Please enter a state: California
New York is already in the list
Enter another name (Y/N): N
Here are the states in the file: California and Georgia

Topics: list and list processing
You will write a program to read grade data from a text file, displays the grades as a 5-column table, and then print the statistics (min, max, median, and median). You can assume that the input file only one number per line. You can assume the user always enter a file that exists.
The median is the value in the middle of a sorted list. To sort a list, use list.sort() function. It’s computed as below.
For a list of odd length, the middle number is just the length divide by 2. For the list, [1,2,3], the median is 2 since 2 is in the middle of the list. The middle index is 3//2, which is 1. Remember that // is the integer division operator.
When the length of the list is even, there are two middle numbers. The median is the average of the two middle numbers. For example, [1,2,3,4], the median is (2+3)/2 = 2.5. The two middle indexes for this example are (4//2)-1 = 1 and (4//2) = 2.

- Laboratory Exercise No. 40 Filename: Lab_exer40 You are tasked to create a program that will get the basic salary of 5 employees from the user and these 5 values should be saved in a list named as basicSalary. The user will then enter the incentive rate (Example. 0.15) The program should compute the net salary. The net salary is computed using the formula basic salary multiplied by incentive rate. Store the computed net salary in another list which will be named as net_salary. Display the values stored in the 2 lists. Example Output: Enter basic salary : 200 Enter basic salary : 300 Enter basic salary : 450 Enter basic salary : 600 Enter basic salary : 750 Enter incentive rate : 0.50 Basic salary [200,300,450,600,750] Net Salary [100,150,225,300,375]arrow_forwardC++ You should create a loop which will ask user if they want to insert, delete, display and exit.

- 1994 Weekly Gas GraphIn the student sample programs for this book, you will find a text file named 1994_Weekly_Gas_Averages.txt. The file contains the average gas price for each week in the year 1994.(There are 52 lines in the file.) Using matplotlib, write a Python program that reads thecontents of the file then plots the data as either a line graph or a bar chart. Be sure to displaymeaningful labels along the X and Y axes, as well as the tick marks. (in python)arrow_forward1.

- Problem Charge Account Validation Create an application that reads the contents of the file into an array or a List . The application should then let the user enter a charge account number. The program should determine whether the number is valid by searching for it in the array or List that contains the valid charge account numbers. If the number is in the array or List , the program should display a message indicating the number is valid. If the number is not in the array or List , the program should display a message indicating the number is invalid. For Visual Studio .Net 4.6.1 current solution on bartleby does not work as it does not actually use a list and does not properly retrieve the file file is a text document with 18 7 digit numbers named ChargeAccounts.txtarrow_forwardCreate a hand of cards using python code: - 52 cards are in the deck To create a hand of cards, first prompt the user for the number of cards to deal between 2 and 5. You must check the users input for the correct value. If the value is incorrect, tell the user, it is incorrect and ask for a new number. Take the number of cards entered by the user and from the deck of cards place those number of cards in the list called hand. Hint: use the pop command to take from the shuffled deck of cards and place into the hand list. Always make sure you have cards left in the deck of cards when creating a hand.arrow_forwardAverage Number of WordsIf you have downloaded the source code from the Computer Science Portal you will find a filenamed text.txt in the Chapter 08 folder.
