$$ # PART A

$$ # $======$

$$ # Create a variable and set its value to the response from an input call asking

$$ # for a filename of a log file $("$What log would you like to parse?"$).$ To test your

$$ # code, you should enter the name of the log file in the repository, which is

$$ # lab$6\_$data$\_$problem$1.$log

$$ ## YOUR CODE HERE ##

$$ # PART B

$$ # $======$

$$ # Using the load$\_$file$\_$into$\_$list function, load the lines from the log file into a

$$ # list variabe named lines

$$ ## YOUR CODE HERE ##

$$ # PART C

$$ # $======$

$$ # You will be looking for unique IP addressed and usernames $($in DOMAIN$\backslash$username

$$ # format$)$ in the log file. Create two lists that will hold these values for display

$$ ## YOUR CODE HERE ##

$$ # PART D

$$ # $======$

$$ # Create a new python regular expression object by compiling an expression to

$$ # look for an IP address

$$ ## YOUR CODE HERE ##

$$ # PART E

$$ # $======$

$$ # Search the contents of each line for an IP address. If there is a match and that match

$$ # doesn't already exist in the list, append it to the list. Remember, IP addresses look like

$$ # $12\mathrm{.}34\mathrm{.}56\mathrm{.}78$

$$ # PART F

$$ # $======$

$$ # Create a new python regular expression object by compiling an expression to

$$ # look for user accounts. User accounts will be in the format DOMAIN$\backslash$username

$$ ## YOUR CODE HERE ##

$$ # PART G

$$ # $======$

$$ # Search the contents of each line for a user account using the regular expression you created.
