Note this isn't the most efficient strategy in terms of the number of operations, but your code should be much more readable that the original.Finish this program from the code posted below! Note: There should be two files Main.py and Contact.py You will implement the edit_contact function. In the function, do the following: Ask the user to enter the name of the contact they want to edit. If the contact exists, in a loop, give them the following choices Remove one of the phone numbers from that Contact. Add a phone number to that Contact. Change that Contact's email address. Change that Contact's name (if they do this, you will have to remove the key/value pair from the dictionary and re-add it, since the key is the contact’s name. Use the dictionary's pop method for this!) Stop editing the Contact Once the user is finished making changes to the Contact, the function should return.

You are going to decode the scrambled word into correct orderin this game. One round of play is as follows:1. Computer reads a text file named words.txt2. Computer randomly picks one word in the file and randomly scrambles characters in the wordmany times to hide the word3. Computer displays the scrambled word to user with indexes and gives the user options to1. Swap two letters in word based on index given2. Solve the puzzle directly3. Quit the game4. If a player chooses to swap letters, the computer reads two indexes and swaps the letters. Thegame resume to step 3 with the newly guessed word. If the resulted word after swapping is thesecret word, the game is over.5. If a user chooses to solve directly, computer prompts the user to enter the guessed word. If it’scorrect, the game is over, otherwise goes to step 3.6. After game is over, display how many times the player has tried to solve the puzzle.The following is sample…

- Task: Loading data from files This exercise will require you to load some information from files and use it in your program. scene.txt contains a description of a series of shapes and colours to draw. You need to write code to read in the file data and draw the requested shapes in the correct colour. Each line in scene.txt will contain one of the following starting keywords followed by some data: COLOUR followed by 3 values: R, G, B CIRCLE followed by 3 values: X, Y, RADIUS RECT Followed by 4 values: X, Y, W, H LINE Followed by 4 values: X1, Y1, X2, Y2 CIRCLES are defined from the center. RECT's are defined from the top left. All values are space separated, and you can assume all input is correct (no errors). Please solve this program to draw the scene. I can't upload the file scene.txt, so I decide to screenshot a file for you. Subject: Java ProgrammingWhen it loads, the list of car objects should be created by reading from the above file.
