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.

Frames Unlimited is a wholesaler that specializes in picture frames. The company stores its product information (each item’s number, name, size and price) in a sequential access file named pictureFrame.txt. You need to create a report using the pictureFrame.txt sequential access file. The report should contain a list of all picture frames with a size of 5×7. The report will be saved to another sequential access file named pictureFrame57.txt. Your first step is to ____. a. determine whether the pictureFrame.txt file exists b. declare a StreamReader variable for the input file c. open the pictureFrame.txt file for input using the OpenText method d. open the pictureFrame57.txt file for output using the CreateText method

Directions: Use a file city.txt for answering the questions that follow each scheduling algorithm. This file has three columns (comma separated): the first column contains the job Id, the second column indicates the CPU burst, and column three is the arrival time of the corresponding job. Parallel Programming It is vaccine season! COVID19 vaccines are out, and everyone is rushing to get one. Vaccines are available from six different brands and you have been entrusted to write a program to count the total number of vaccines of each brand administered across 21 cities in the state. Write a multithreaded program (in the file vaccines.cpp) that counts the number of vaccines in 21 different files of numbers. Each line in each of the files will contain either one of the following brand names: v1, v2, v3. Your program must count the number of units for each vaccine brand administered, across all 21 cities, and display the total number of units for each brand. The files are named…

Last lab, we modified the inventory program to write a file. This lab, we’ll modify it to read a file. First, take your program from the last lab. Add one more feature: at the end, just before you close the file, write the word “END” all by itself on a line. Run that program once to create a file of items with “END”. Now, copy that program to a new file cp lab7.cpp lab8.cpp so you can use it as a basis for this lab. Modify lab8 so instead of reading from cin and writing to a file, you read from your file and write to cout. The only tricky part is deciding when to stop reading. In lab7, you stopped reading when the user said they didn’t want to continue. For lab8, keep reading until you read “END” for the name of the produce. You can use “==” on strings, so if (product name == ”END”) will tell you that you can stop reading. PHOTO OF WHAT IT SHOULD LOOK LIKE INCLUDED My code for last lab: #include <iostream>#include <string>#include <fstream>using namespace std; int…
wordSort.py: Write a program that reads words from a file (filename given as a command-line argument) and prints them in (case insensitive) sorted order. For example, if the input file contains:If there's a problem yo I'll solve itCheck out the hook while my DJ revolves itIce ice baby The program should print (one word per line, compressed here for brevity):a baby Check DJ hook I'll Ice ice If it it my outproblem revolves solve the there's while yo
Please in C Language Write a program that uses an existing text file (text.txt) to determine the number of occurrences of each letter.
