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 Programming

Python - 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.

In C++ (don't copy paste the same answer that is already on this site, post unique code) Structures A menu-driven program gives the user the option to find statistics about different baseball players. The program reads from a file and stores the data for ten baseball players, including player’s team, name of player, number of homeruns, batting average, and runs batted in. (You can make up your data, or get it online ) Write a program that declares a struct to store the data for a player. Declare an array of 10 components to store the data for 10 baseball players. The program prints out a menu (in a loop, so this can be done again and again) giving the user a choice to: print out all users and statistics print out the statistics for a specific player print out all data for a specific team update the data for a particular player (change one of the statistics) DO ALL WORK IN FUNCTIONS. USE A FUNCTION TO READ THE DATA, A FUNCTION TO PRINT THE MENU, and FUNCTIONS FOR EACH OF THE MENU…
A 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:
The function print_last_line in python takes one parameter, fname, the name of a text file. The function should open the file for reading, read the lines of the file until it reaches the end, print out the last line in the file, report the number of lines contained in the file, and close the file. Hint: Use a for loop to iterate over the lines and accumulate the count. For example: Test Result print_last_line("wordlist1.txt") maudlin The file has 5 lines.
PYTHON: I need to get the avg statement out of the loop so that the output prints correctly. Any suggestions. Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20. The program performs the following tasks: Read the file name of the tsv file from the user. Open the tsv file and read the student information. Compute the average exam score of each student. Assign a letter grade to each student based on the average exam score in the following scale: A: 90 =< x B: 80 =< x < 90 C: 70 =< x < 80 D: 60 =< x < 70 F: x < 60 Compute the average of each exam.

Slide Type Slide • Exercise # 4 A hotel salesperson enters sales in a text file. Each line contains the following, separated by semicolons: • The name of the client, the service sold (such as Dinner, Conference, Lodging, and so on), • The amount of the sale, and the date of that event. • Write a program that reads such a file and displays the total amount for each service category. Display an error if the file does not exit or the format of the record is incorrect. No need to display anything else in this regard. Note that you can assume that the dates are entered correctly (no need to validate them). You may also assume that the name of the input text file is inputex4.txt. • Make sure you use a dictionary in your solution. • Sample run is included below for the given input file inputex4.txt Summary of total sales according to services Dinner 634.75 Conference 1133.25 Lodging Dinner and Lodging 550.25 625.14 Slide Tyne Fragment v
PROGRAM NEEDS TO MATCH EXAMPLE PHOTO Write a program ( lab6.cpp ) that gives and takes advice on program writing. The program starts by writing a piece of advice to the screen and asking the user to type in a different piece of advice. The program then ends. The next person to run the program receives the advice given by the person who last ran the program. The advice is kept in a file, and the contents of the file change after each run of the program. You can use your editor to enter the initial piece of advice in the file so that the first person who runs the program receives some advice. Allow the user to type in advice of any length so that it can be any number of lines long. The user is told to end his or her advice by pressing the Return key two times. Your program can then test to see that it has reached the end of the input by checking to see when it reads two consecutive occurrences of the character ‘\n’. Hints:- You need to look at each character as it is read to see if it is…

Python please: Given a text file named RandomTextFile.txt that contains newline characters, write a program that removes all the newline characters from the file. Your program should use the filename as input, and the output file should use the same filename as the original. Use the attached file RandomTextFile.txt to help you write and test your program. It contains the following text: Python is an interpreted language and the python interpreter is a computer program that executes code written in the python programming language. The python interactive interpreter is useful for simple operations or programs consisting of only a few lines. For more lines, a programmer can write Python code in a file, and then provide that file to the interpreter. For normal development a programmer installs python as an application on a local computer. Macintosh and Linux operating systems usually include python, while Windows does not. Programmers can download the latest version of python for free from…
