- In Chapter 11, you created the most recent version of the MarshallsRevenue program, which prompts the user for customer data for scheduled mural painting. Now, save all the entered data to a file that is closed when data entry is complete and then reopened and read in, allowing the user to view lists of customer orders for mural types.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…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 'a' mode appends new data to the end of an existing file. But if the file is nonexistent, it does not create a new one to append the data.True or FalseSolve in Python Include Screenshots of Input and Output For this lab, you will write a program that creates and edits a test file called users.txtYour program should implement the following functions: add_user – Accepts a username as an argument and adds it to the file update_user – Accepts an old username and a new username as separatearguments and replaces any instance of that the old username with the newusername in the file. remove_user – Accepts a username as an argument and removes the userfrom the fileUse the following code to test your program:add_user(“bob”)add_user(“joe”)add_user(“ann”)add_user(“mike”)update_user(“joe”, “jo”)remove_user(“ann”)Your final file should look like:bobjomikeYour submission should include your source code (.py file) and either yourfinal text file or a screenshot of it.my_list.txt: 150+250 Which of the following code blocks writes the sum (400) in a new line of the file? a. with open('my_list.txt', 'r+') as file: line = file.readline() sum = 0 for i in line.split('+'): sum = sum + i file.write(str(sum)) b. with open('my_list.txt', 'r+') as file: line = file.readline() for i in line.split('+'): sum = sum + int(i) file.write(str(sum)) c. with open('my_list.txt', 'r+') as file: line = file.readline() sum = 0 for i in line.split(): sum = sum + int(i) file.write(str(sum)) d. with open('my_list.txt', 'r+') as file: line = file.readline() sum = 0 for i in line.split('+'): sum = sum + int(i) file.write(str(sum))

- 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.Please code in pythonWrite a function to diaply the total word count in a file. Input parameter for the function will be a single filename. imports allowed1. os2. random3. stringComputer Science Objective You have a compressed file named `gzamlet.Z` of gzip type in Lempel-Ziv (LZ77) encoding. File contains Shakespeare's play Hamlet. Write a command that finds the line number of the text file where the iconic phrase "To be, or not to be" is found. Count the blank lines in your tally. Constraints =========== - You are prohibited from using intermediate files. You must place an order and/or use tubes. index ====== - The `zcat` command allows you to decompress an archive and send its contents to standard output.
