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.

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…
Directions: Typing make at the command line should create executable named bitflip. Only bitflip.c and Makefile are included in the input unless permission is given for any other files. Program should have consistent indentation. Code should be readable with good variable and function names. No use of "break or continue statements" except in a switch. Program must exit with a return code of 0 on success and an error code in other cases. The program used getopt to parse the command line. Whenever an error occurs on the command line the user is given the usage statement and an appropriate error message if needed. If the -o option is used the output will go to a file named as specified without changing the filename at all otherwise it will go to stdout. -e option works as specified using bitwise operations. -f option works as specified using bitwise operations. -a option works as specified using bitwise operations. -s option works as specified using bitwise operations.

Prog 1. File Encryption: File encryption is the science of writing the contents of a file in a secret code. Your encryption program should work like a filter reading the contents of one file, modifying each character in the input file into a code, and then writing the coded characters out to a second file. The second file will be a version of the first file but written in a secret code. In Notepad or something similar, you will create a file with text in it. It should be several lines long. Your program should read the file character by character and make some change to the character before writing that character to a second new encrypted file. See program 13-8 to see how to read and write one character at a time. You may come up with an encryption technique of your own or use something simple like adding 10 to the ASCII code of each character in the file before it is written to the second file.
