Chapter 14, Problem 1E

In python, the shelves access mode _____ will create a file for reading or writing. If the file exists, its contents are over written.     true or false?   a. "c" b. "n" c. "r" d. "a"   disregard true or false.

Instructions Add a command to this chapter’s case study program that allows the user to view the contents of a file in the current working directory. When the command is selected, the program should display a list of filenames and a prompt for the name of the file to be viewed. Be sure to include error recovery in the program. If the user enters a filename that does not exist they should be prompted to enter a filename that does exist. An example of the program input and output is shown below: /root/sandbox 1 List the current directory 2 Move up 3 Move down 4 Number of files in the directory 5 Size of the directory in bytes 6 Search for a file name 7 View the contents of a file 8 Quit the program Enter a number: 7 Files in /root/sandbox: filesys.py example.txt Enter a file name from these names: example.txt THIS IS CONTENT OF AN EXAMPLE FILE. /root/sandbox 1 List the current directory 2 Move up 3 Move down 4 Number of files in the directory 5 Size of the directory in bytes 6…

in c# i need to Write the program named DirectoryInformation that allows a user to continually enter directory names until the user types end. If the directory name exists, display a list of the files in it; otherwise, display the following message, Directory foo does not exist, to indicate the directory does not exist (foo would be the name of the directory to be checked) . Create as many test directories and files as necessary to test your program. An example of the program is shown below: Enter a directory >> lorem lorem contains the following files lorem/ipsum.txt Enter another directory or type end to quit >> foo Directory foo does not exist

Design an application that can be used to read DVD titles from a text file. You do not have to write to the file, only write code to read the titles of DVDs from a text file called DVD.txt

You develop a Python application for your school.You need to read and write data to a text file. If the file does not exist, it must be created. If the file has content, the content must be removed.Which code should you use? Group of answer choices C. open(“local_data”, “w+”) D. open(“local_data”, “w”) A. open(“local_data”, “r”) B. open(“local_data”, “r+”

CODE IN PYTHON PLEASE The objective is to create a code in Python that can extract the columns highlighted in blue (Column T and AB3) and output them to a .txt file. The code should be able to generate the text file with the columns that are highlighted in blue and store them on a separate folder. Below shows how the Test.xlsm file looks like as well as how the text file should look like when the code extracts and outputs it. Google drive to access Test.xlsm file: https://drive.google.com/drive/folders/16utzb5_h7yMCN8_13E_JqasfcpykZOYr?usp=sharing What my code outputs is shown in the picture (O1.png) What I would like for my code to output is the columns next to each other (Right Example.png) The current code is able to output Columns T and AB3 but I am not able to output them next to each other as shown above. We would also like for the code to be capable of storing the text file to a separate folder. Below is the code I have been working on. #package to read xlsm file import openpyxl…

Using Java, Write an interactive console application for an employee management service. The user can enter the following options for the apps 1-List all employees, sorted by Name. 2-Hire a new employee (add to list) 3-show the lowest salary and highest salary and average of the salaries 0-exit - At the beginning of the application, data will be read from a text file. - And at the end of it when user chooses 0, data will be saved to the same file. - The date format needs to be YYYY-MM-DD and The fields needs to be separated by semicolon(;) Example of data in the text file : Alice P.;2012-09-22;Shoes;40 Emma W.;2016-07-07;Furniture;30 Eva;2021-08-08;Pizza;50 EmployeeSchedule class has the following attributes private String name; private String department; private Date dateHired; private double hourSalary; name : between 2-50 characters and not permitted to have ;^?@!~* department : between 2-50 characters and not permitted to have ;^?@!~* dateHired : between 1900 and 2100 salary :…

Task1: Create a directory say, "Linux user" and it contains three files (e.g.; A, B, C). Change the directory permission first for "user", “group", “others", “all" then change the permission of files residing in the same folder/directory.
