A company stores payment information for their employee working on a project and paid on a project basis, in a text file whose name is entered through keyboard (see a sample input file below). The first line of the file indicates the number of employees and each subsequent line corresponds to information related to an employee payment (employee name, number of hours worked and his/her hourly wage). Write a python program that reads such a file and displays the employees' names, their hours worked, and their salaries. Finally, it displays the total payment. Your program should consider the following erroneous cases: • The file does not open/exist The format of the data in the file is incorrect (e.g. hours = "1-" or salary = "unkown") in which case a RuntimeError exception should be raised and the processing should continue

Exercise 5: Write a python program that reads from a text file whose name is provided by the user (see a sample below) blood glucose readings recorded during the last week. Each line contains a certain number of blood glucose readings followed by the patient id. Your program should then display for each patient, their id number, the number of readings, the average value of the readings followed by the patient status (Normal range: 90–120 mg/dl, Low range: less than 90 mg/dl, High otherwise). Your program should consider the following erroneous cases and display appropriate message as shown in the sample output below: • The file does not open/exist • The readings are invalid (non-integer values or negative) or missing, in which case a ValueError exception should be raised and the processing should continue. Enter input filename: patients.txt Patient Id #Readings Average Status ========== ========= ======= ====== 120 150 150 P1111 P1111 3 140 High 100 90 90 100 P2222 P2222 4 95 Normal…
Code should be in Python. Given a text file containing the availability of food items, write a program that reads the information from the text file and outputs the available food items. The program first reads the name of the text file from the user. The program then reads the text file, stores the information into four separate lists, and outputs the available food items in the following format: name (category) -- description Assume the text file contains the category, name, description, and availability of at least one food item, separated by a tab character ('\t'). (Examples in image)
Using Python: program6_1.pyWrite a program that uses a text file to store weekly payroll data for the office. The program should enable the user to enter the name, hourly pay rate, and weekly hours for a number of office employees. The pay rate and hours should be type float, and each datum should be written to its own line in the file. Enter data for at least five employees and then close the file.Sample Output See image below program6_2.pyThis program reads the text file created in the program above and then calculates and prints each employee's weekly pay. Note the currency format with commas for thousands. The program should finish by printing the total payroll for the office.Sample Output see image below
Python please: The provided file "wgucourse.py" is a module that functions as a simple course catalog. The module defines three courses and stores a variety of course details inside each. Write a program that a) imports the module, b) reads a course from user input, and c) prints the course details in the following format: [course] Course duration: [duration] Number of Quizzes: [quizzes] Is there a pre exam? [pre_exam] For example, if the input is: C859 the output should read: C859: Professional Programming in Python Course duration: 6 weeks Number of quizzes: 6 Is there a pre exam? True

Problem Definition Task. Your task is to develop a python program that reads input from text file and finds if the alphanumeric sequence in each line of the provided input file is valid for Omani car license plate. The rules for valid sequences for car plates in Oman are as follows: Each sequence is composed of 1 to 5 digits followed by one or two letters. Digits cannot start with 0, for instance, 00, 011, or 09 are not valid digit sequences. The following list are the only valid letter combinations: ['A','AA','AB','AD','AR','AM','AW",'AY"', 'B', BA','BB','BD',"BR','BM',"BW',"BY', 'D','DA','DD','DR','DW','DY', 'R','RA','RR','RM','RW','RY', 'S','SS', 'M','MA','MB','MM','MW','MY", "W',"WA',WB',"wW', Y,YA','YB','YD','YR','YW',YY] Program Input/Output. Your program should read input from a file named plates.txt and write lines with valid sequences to a file named valid.txt. Any line from the input file containing invalid sequence should be written to a file named invalid.txt. Each line…
Language: Java 1. The sample input will have to be in Text File (.TXT) 2. By using the first function, this program reads score and name values from a file. The program then determines the grade for each students by using the second function. Finally, the program displays the name, score, and grade information on the console. The two functions are shown in the images attached below:
In C language, create a program that uses a standardized input method (input file with From To and Weight defined) to read in a text file. The text file will contain the name of the building and the distance from each building when running the program with the file, the program will read the information above and will ask users which buildings are they in and where they want to go to find the shortest path. then it will display the shortest route and the distance from the building that the user is at to the building that the user wants to go to

Write a c++ program in which you will keep a record of all transactions (deposit/withdrawal) happening in a bank. Create a text file containing information of all accounts in a bank. Load this information into a struct array at the start of the program. Make a menu for the following options Make a Transaction Deposit Withdrawl View all Transactions Make a Transaction: Once this option is selected, show two more options for Deposit and Withdrawl. Whatever option is selected by the user, your program should then ask for account ID, verify if its exist, and then ask for the amount. Update the balance in the account variable in struct array by adding or subtracting the transaction amount. Make a log of all transactions by storing the transaction details into a binary file. Transaction details should include Date and Time of transaction, Account#, Type of Transaction, and Amount of Transaction Use the binary file in Append mode in order to keep the previous data View all…
Complete the following incomplete program (begin by copy-pasting that into a new program file). The completed program will provide a user interface to draw as many circles as the user wants only by clicking in the window. After getting the number of circles (n) to draw as input from the user through the provided interface, the program should iterate n times. In each iteration it should wait for the user to click twice and draw a circle with center at the point where the user clicked first and with radius calculated as its distance from the second point where the user clicked. It should then fill the circle with a random color. Hints: Distance between two points with coordinates x1 & y1 and x2 & y2 and can be calculated as sqrt((x1-x2)2 + (y1-y2)2 ). To generate a random color, use randint(0,255) from the random libray to generate a random number between 0 and 255 (both inclusive). Use it three times to get the r, g and b values to generate a random color from graphics import…
