Solve 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.txt Your 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 separate arguments and replaces any instance of that the old username with the new username in the file. remove_user – Accepts a username as an argument and removes the user from the file Use 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: bob jo mike Your submission should include your source code (.py file) and either your final text file or a screenshot of it.

Include Screenshots of Input and Output
For this lab, you will write a program that creates and edits a test file called users.txt
Your 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 separate
arguments and replaces any instance of that the old username with the new
username in the file.
remove_user – Accepts a username as an argument and removes the user
from the file
Use 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:
bob
jo
mike
Your submission should include your source code (.py file) and either your
final text file or a screenshot of it.
