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…
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

LAB ASSIGNMENTS IMPORTANT: you need to complete the PDP thinking process for each program. The example program downloads, opens and reads a file, hosted at this address: https://www. w3.org/TR/PNG/iso_8859-1.txt web_scraping 1.py - write a program to download a .txt file from online, open and read the file, and then display the output. Note: you do NOT have to display the whole file or write to a .txt file (optional). You need to use a different .txt file. 120 The following are the graphical (non-control) characters defined by ISO 8859-1 (1987). Descriptions in words aren't all that helpful, but they're the best we can do in text. A graphics file illustrating the character set should be available from the same archive as this file.

PYTHON!!!! Write a program that allows the user to navigate the lines of text in a file. The program should prompt the user for a filename and input the lines of text into a list. The program then enters a loop in which it prints the number of lines in the file and prompts the user for a line number. Actual line numbers range from 1 to the number of lines in the file. If the input is 0, the program quits. Otherwise, the program prints the line associated with that number. An example file and the program input and output is shown below: example.txt Line 1. Line 2. Line 3. Enter the input file name: example.txt The file has 3 lines. Enter a line number [0 to quit]: 2 2 : Line 2. The file has 3 lines. Enter a line number [0 to quit]: 4 ERROR: line number must be less than 3. The file has 3 lines. Enter a line number [0 to quit]: 0 The program works as expected for given input, test 1: Custom Test: Delete file at start Test Contents: import os.path try: os.remove('.test.txt')…
C++ 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.
Why doesn’t the following pseudocode module work as indicated in the comments? // The readFile method accepts a string containing a filename as // an argument. It reads and displays all the items in the file. Module readFile(String filename) // Declare an input file. Declare InputFile file // A variable to hold an item that is read from the file. Declare String item // Open the file using the filename. Open file filename // Read all the items in the file and display them. While eof(file) Read file item Display item End While End Module
