The file consists of Tags, Timestamps, Members, Users, and Messages. Because there are multiple members you will need to create a Unique members list that hold the name of the unique members as well as unique tags. The class should contain the following tags that will return the information above:…I am looking for the following in your program: Python GUI-based MP3 Player Project #3: Python GUI-based MP3 Player 1. Ability to select a folder / directory for MP3s. (HINT: There’s a function/method in filedialog of tkinter to do this. In other words, you'll need the following import: from tkinter import messagebox, filedialog 2. Ability to play selected MP3s. 3. Ability to pause the current MP3. 4. Quit button/function to exit application. 5. Use a list to store and display the mp3 file names. You will need to demonstrate your mastery of lists, loops, and GUI elements within this program. Submission will include: 1. Python program named myplayer.py 2. Data Flow Diagrams / Pseudocode 3. If choosing an alternate library to tkinter or pygame, provide instructions and download links for the alternate library.4.14 LAB: JavaScript game object Create an object called game in the script.js file. Add 2 properties: lives - initially 3, and coins - initially 0. Add a getter called points that returns coins * 10. Add a playerDies() method that subtracts 1 from lives if lives is greater than 0. Add a newGame() method that sets lives to 3 and coins to 0. The script.js file includes several console.log() statements, which should match the output below if the game object works correctly. lives = 3 coins = 0 points = 0 points = 20 lives = 2 lives = 0 lives = 3 coins = 0 View the program's output in the browser's JavaScript console.
- 1. Create a folder named LastName_FirstName (ex. Reyes_Mark) in your local drive.2. Create a new project named LabExer6A. Set the project location to your own folder.3. Create a simple guessing game (similar to Hangman or Hangaroo). In this game, the user guessesa letter and then attempts to guess the word.4. Create a Notepad file named words.txt which will store any number of words each written per line.5. The Java program shall: randomly select a word from the list saved in words.txt; display a letter in which some of the letters are replaced by ?; for example, ED??A??ON (for EDUCATION); place the letter in the correct spot (or spots) in the word each time the user guesses a letter correctly; inform the user if the guessed letter is not in the word; and display a congratulatory message when the entire correct word has been deduced.Write a Java GUI application that will keep track of a user’s contact list.
