Next, write another script named Q$1$B$.$py$,$ that receives as a parameter $($on the command line$)$

the name of a $.$py file in the current directory, e$.$g$.,$ x$.$py$.$

Q$1$B$.$py should check two things:

$1)$ Is the given Python file a script $($i$.$e$.,$ is it intended to be run directly$)?$

a$.$ For our purposes, a Python file is considered a script if it contains an

if $\_\_$name$\_\_==\_\_$main$\_\_$: statement

$2)$ Is it uninfected $($i$.$e$.,$ does it not yet contain the virus code$)?$

If both checks are true, then the Q$1$B script should re$-$write the input script $($e$.$g$.,$ x$.$py$),$ so that

the new $$x$.$py$$ will contain a Python script with the same functionality as of the original x$.$py$,$

except that the new script will also perform the following simple spyware payload functionality:

Whenever the new $$x$.$py$$ script is run, it appends, to the end of a file called Q$1$B$.$out, a line

containing the entire command line used to invoke it$,$ i$.$e$.,$ the file$/$script name $($x$.$py$)$ followed

by the arguments $($parameters$)$ with which the script $($x$.$py$)$ was run, if any. If Q$1$B$.$out does not

exist when the new $$x$.$py$$ is run, then $$x$.$py$$ should create Q$1$B$.$out.
