If the file’s contents won’t fit on a single screen, the program should display 24 lines of output at a time, and then pause. Each time the program pauses, it should wait for the user to strike a key before the next 24 lines are displayed.

- 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 Programmingarrow_forwardData File: Example #1AAAAABBBBBCCCCCDDDDDAAEBCBAFBBCDCECDADDEFEEFFFExample #2AAATAABTBBBBCCCCTCDDTDDDAASAABBSBBCCSCCDSDDDEEEAEEFBFFFDDF Write a program that will give the user a brief introduction, then allow the user to type in the name of the file to be analyzed, the name of the data file to generate, and then process the data to match the output that is shown below. This DNA test measures the various parts of the sequence and assigns them a letter. While the letters could be anything from A to Z, the only letters that matter for this test are the letters {A,B,C,D} all other letters can be ignored completely. A sample will be tested, given a length of time and then tested again. Each time the scientist will generate a line of data. Here is one Example: Example #1 AAAAABBBBBCCCCCDDDDD AAEBCBAFBBCDCECDADDEFEEFFF At first glance the sample looks significantly different after the second test. But if you look at the data, you will note that since we only care about A,B,C,D’s that the…arrow_forwardFinish 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. Code:from Contact import Contactimport pickledef load_contacts():""" Unpickle the data on mydata.dat and save it to a dictionaryReturn an empty dictionary if the file doesn't exist """try:with open("mydata.dat", 'rb') as file:return…arrow_forward
- Line Numbers Write a program that asks the user for the name of a file. The program should display the contents of the file with each line preceded with a line number followed by a colon. The line numbering should start at 1. Pythonarrow_forwardIn C# create an application that writes a series of random numbers to a file. Each random number should be in the range of 1 through 100. The application should let the user specify how many random numbers the file will hold.arrow_forwardC++ Create a program that reads a file containing a list of songs and prints the songs to the screen one at a time. After each song is printed, except for the last song, the program asks the user to press enter for more. After the last song, the program should say that this was the last song and quit. If there were no songs in the file to begin with, the program should say that there are no songs to show and quit. The program should begin by asking the user for the name of the input file. Each song consists of a title, artist, and year. In the file, each song is given on three consecutive lines. Create this program using a class Song.arrow_forward
- A MyPetStore sells many pets and their accessories. As new pets are added to the MyPetStore, theirinformation is entered into a flat text file. Each month, the manager requests a listing of all pets sorted bytheir price. You must write a program to produce a report of MyPetStore and their types sorted by their pricesfrom the data in the flat text file. Below is a description of the information on the text file:• The first entry is the number of animals on the file (numeric) •The fields below repeat for each animal:o Pet name (String)o Birthdate (java.time.LocalDate)o Price (numeric)o Species Type (String)o Special feature (boolean or String)The animals sold by the MyPetStore are of six types: Dogs & Cats, Reptiles, Birds, Rabbits & SmallAnimals.For Dogs & Cats, the special feature field on the flat file is the breed of the animal (String).For Reptiles, the special feature field is the blood type (warm vs cold-blooded, String).For Birds, the special feature field is the…arrow_forwardInstructions The Clay Hill Golf Club has a tournament every weekend. the club president ask you to write two programs: 1. a program that will read each player's name and golf score as keyboard input, then save those records in a file named golf.txt. (each record will have a field for the player name and a field for the player's score.) allow for any number of players and scores to be input. 2. a program that reads the records from the golf.txt file and displays them. Be sure to use clear prompts/labeling for input and output.arrow_forwardA Personal Fitness Tracker is a wearable device that tracks your physical activity, calories burned, heart rate, sleeping patterns, and so on. One common physical activity that most of these devices track is the number of steps you take each day. The steps.txt file contains the number of steps a person has taken each day for a year. There are 365 lines in the file, and each line contains the number of steps taken during a day. (The first line is the number of steps taken on January 1st, the second line is the number of steps taken on January 2nd, and so forth.) Write a program that reads the file, then displays the average number of steps taken for each month. (The data is from a year that was not a leap year, so February has 28 days.) You don't need to see the file , Just write a code using the "file" like this def main(): with open("steps.txt", "r") as file:arrow_forward
- Body Mass Index Write a program that reads names, weights, and heights from bmi.dat (provided with starter code; do not change the file name). Use the information to calculate and displays a person’s body mass index (BMI). The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height. A person’s BMI is calculated with the following formula: BMI = weight × 703 / height2 where weight is measured in pounds and height is measured in inches. The file is in the format name weightInKG heightInCM You will read the name, weight and height for 4 people from the file, and you will need to convert the weights in the file to pounds (note that 1 kilogram = 2.2 pounds) and the heights to inches (2.54 cm = 1 inch). The program should display the person's name along with the calculated BMI and a message indicating whether the person has optimal weight, is underweight, or is overweight. Your output should look like A person’s weight…arrow_forwardPython - Next Birthdate In this task, we will write a program that reads birthdate data from a given CSV file, and given the current date, determines which person's birthday will be celebrated next. Create a function with the following signature: nextBirthdate(filename, date) filename: parameter, which represents the CSV filename. date: parameter, which represents the current date. The function should open the CSV file, read the birthdate data, and determine which person's birthday will be celebrated next, given the current date. The name of the person should be returned. In other words, given a date, find the person whose birthday is next. Sample Run birthdates.csv Draven Brock, 01/21/1952 Easton Mclean, 09/02/1954 Destiny Pacheco, 10/10/1958 Ariella Wood, 12/20/1961 Keely Sanders, 08/03/1985 Bryan Sloan,04/06/1986 Shannon Brewer, 05/11/1986 Julianne Farrell,01/29/2000 Makhi Weeks, 03/20/2000 Lucian Fields, 08/02/2018 Function Call nextBirthdate("birthdates.csv", "01/01/2022") Output…arrow_forwardNeed this done in C# Microsoft Visual Studio.
