In process$\_$file:

$1.$ Comment out all the print statements only

$2.$ Above the for loop make two variables

$$ curr$\_$week $=0$

$$ words$\_$per$\_$week $=[[],[],[],[],[],[],[],[],[],[],[]]($this is your list of $11$ lists$)$

$3.$ Inside the for loop:

$$ Inside the if$($line$[0$:$3]==$URL$)$:

$$ add $$curr$\_$week $=$ get$\_$week$($line$)$

$$ Inside the else

$$ To find the list we need to append to we can do:

words$\_$per$\_$week$[$curr$\_$week$]$

$$ then we want to use the method $.$append$()$ to append our $.$strip$()$ed and $.$lower$()$ed word

$$ In main store the value of process$\_$file and print it out. It will just look

like a print dump.
