Employee Management System
This exercise assumes you have created the Employee class for
■ Look up an employee in the dictionary
■ Add a new employee to the dictionary
■ Change an existing employee's name, department, and job title in the dictionary
■ Delete an employee from the dictionary
■ Quit the program
When the program ends, it should pickle the dictionary and save it to a file. Each time the program starts, it should try to load the pickled dictionary from the file. If the file does not exist, the program should start with an empty dictionary.

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.…

Implement a menu driven program that has some operations for a food truck. A food truck has multiple food items as well as a menu which contains a selection of the food items which will be sold for that day. A maximum of 10 food items can appear on the menu for any day. For each food item keep a code, description, category, price and quantity in stock (code, description and category are not usually changed).
Create a comma delimited text file called "items.txt" for 15 or more food items, indicating the item's description, category, price and quantity in stock.
Read all the food items from the text file “Items.txt”
Display all the food items available for this food truck.
Continuously prompt the user for a food item’s code to be placed on the menu until the menu is full or the user enters -1. Note that only food items which have a positive quantity in stock may be added to…

Above all else, it tests your ability to design and then implement a solution to a problem using these concepts. Assignment Overview You are required to design and implement a "Word Game" program in which the user must identify a randomly selected "password" from a list of 8 words. The 8 words are selected at random from the list of 100 words in the starter file (word_game.py) provided to you with this assignment brief. Please use the starter file as the basis of your assignment code. The user has 4 attempts in which to guess the password. Whenever they guess incorrectly, they are told how many of the letters are the same between the word they guessed and the password. For example, if the password is "COMEDY" and…arrow_forward
