a moment to download the script and note the contents. You will find a test string and a list. Both contain entries from the file $/$etc$/$passwd:

arthur:x:$1001$:$1001$:Arthur Smith:$/$home$/$arthur:$/$bin$/$bash

where:

arthur $-$ username

x $-$ indicates encrypted password

$1001-$ UID

$1001-$ GID

Arthur Smith $-$ Comment

$/$home$/$arthur $-$ home directory

$/$bin$/$bash $-$ shell

Add the following to q$2-$passwd.py:

$1.$ A Docstring with your name and student ID$.$

$2.$ A new function. Your function should:

a$.$ Take a string as an argument $($such as test$\_$strn$).$

b$.$ Split the string by the appropriate character

c$.$ If the userid is the same as groupid, return True.

d$.$ Otherwise, return False.

$3.$ Inside the main block delete the $...$

$4.$ Call your function with test$\_$strn as an argument. Print the result, and verify that it is correct.

$5.$ Next, use a loop to iterate through each line of from$\_$passwd.

$6.$ For each iteration of the loop print either:

a$.$ "arthur is a regular user" $($for example, for the user arthur$)$ if your function returns True. Or:

b$.$ "arthur is not a regular user" if your function returns False.

c$.$ Finally, as a comment answer the following:What happens if the number of fields in a string changes? For example, if the first line has $7$ fields but the next line has $6.$ What error will you get? How can you prevent this from causing an error?

Save your changes to the file and attach it below for evaluation.
