I need help resolving this error:

execute$([\text{'}$KITH$-2017\text{'},\text{'}--$test'$])$ did not print out an error message

$35.$ Implement execute

The main application function is execute. It takes the command line arguments and decides whether to call discover$\_$violations or tests.test$\_$all$().$ If the user provides a data file, the function runs discover$\_$violations. If the user provides the argument $--$test it runs the main test function.

You have already seen an example of something similar in the course videos. The application to$\_$celsius contains a function execute that can either be used to test the function or run the temperature application. This code is available in the samples folder under unit$3.$ Take a look at this sample code now and use it to complete your execute function.

When you have finished this function, run the test script. Better yet, try to run the tests directly from the application as follows:

codio@mike$-$panther:~$/$workspace$ python auditor $--$test

Testing module utils

$...$

def execute$($args$)$:

$"""$

Executes the application or prints an error message if executed incorrectly.

The arguments to the application $($EXCLUDING the application name$)$ are provided to

the list args. This list should contain either $1$ or $2$ elements. If there is one

element, it should be the name of the data set folder or the value $\text{'}--$test'. If

there are two elements, the first should be the data set folder and the second

should be the name of a CSV file $($for output of the results$).$

If the user calls this script incorrectly $($with the wrong number of arguments$),$ this

function prints:

Usage: python auditor dataset $[$output$.$csv$]$

This function does not do much error checking beyond counting the number of arguments.

Parameter args: The command line arguments for the application $($minus the application name$)$

Precondition: args is a list of strings

$"""$

# Total arguments

n $=$ len$($args$)$

# Print an error if the number of arguments is incorrect

if n $<1$ or n $>2$:

print$(\text{'}$Usage: python auditor dataset $[$output$.$csv$]\text{'})$

return

if n $==1$:

if args$[0]==\text{'}--$test':

# Call the test procedure header

print$("$Running test procedure..."$)$

else:

print$("$Folder name:", args$[0])$

else:

folder$\_$name $=$ args$[0]$

csv$\_$file$\_$name $=$ args$[1]$

# Check if the second argument is $\text{'}--$test' or a valid CSV file name

if csv$\_$file$\_$name $!=\text{'}--$test' and not csv$\_$file$\_$name.endswith$(\text{'}.$csv$\text{'})$:

print$(\text{'}$Invalid second argument. Should be $"--$test" or a valid CSV file name.$\text{'})$

return

print$("$Folder name:", folder$\_$name$)$

print$("$Csv file name:", csv$\_$file$\_$name$)$
