tep 1 - File Create --- Create two files (file1.txt and file2.txt). Step 2 - File Data --- In file1.txt add the following numbers, each on its own line (1, 33, 32, 55, 66). Do not add data to file2.txt. Step 3 - Write the program. Create a new .py file that reads in the data from file1 and adds all together. Requirements 1. Use a try/except when reading and writing from the files. Check to see if the file exists. 2. Use a main function.

(Inventory) Create an ASCII file with the following data, or use the shipped.dat file available on this book’s Web site. The headings aren’t part of the file but indicate what the data represents Using this data file, write a C++ program that reads the file and produces a report listing the shipped date, part number, first name, last name, and company name.
(Data processing) a. Write a C++ program that opens a file and displays its contents with line numbers. That is, the program should print the number 1 before displaying the first line, print the number 2 before displaying the second line, and so on for each line in the file. b. Modify the program written in Exercise 6a to list the file’s contents on the printer assigned to your computer.

Code should be in Python. A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output. (Examples in image)
Use Scanner and File to read input from a file. Use PrintStream and File to write output to a file. Write and call methods that accept parameters and return values to manage information flow and add structure to programs. Follow prescribed conventions for spacing, indentation, naming, and comments. Notice that if an input file is not found, either for creating a mad-lib or viewing an existing one, the user is re-prompted. No re-prompting occurs for the output file. If the output file does not already exist, it is created. If it does already exist, its contents are overwritten. (These are the default behaviors in Java.) You may assume that the output file is not the same file as the input file. When you are viewing an existing mad lib story, you are simply reading and echoing its contents to the console. You do not need to do any kind of testing to make sure that the story came from a mad lib input file; just output the file's contents. Menu options can be chosen in any order and are…

The ____ file stream data type is for output files, input files, or files thatperform both input and output.
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…

Chapter 4. PC #14. Line Numbers (page 265) 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.
The python function get_second_line takes one parameter, fname, the name of a text file. The function should open the file for reading, determine the second line of the file, close the file, and return the second line (a string). NOTE: You may assume the file will have at least two lines.
