Exercise $11$: Your task. $($basket$\_$rules$\_$test: $4$ points$).$ Your final task in this notebook is to mine this dataset for pairwise association rules. In particular, your code should produce $($no pun intended!$)$ a final dictionary, basket$\_$rules, that meet these conditions $($read carefully!$)$:

The keys are pairs $($a$,$b$)$

$,$ where a

and b

are item names $($as strings$).$

The values are the corresponding confidence scores, conf$($a$$b$)$

$.$

Only include rules a$$b

where item a

occurs at least MIN$\_$COUNT times and conf$($a$$b$)$

is at least THRESHOLD.

Pay particular attention to Condition $3$: not only do you have to filter by a confidence threshold, but you must exclude rules a$$b

where the item a

does not appear "often enough." There is a code cell below that defines values of MIN$\_$COUNT and THRESHOLD, but your code should work even if we decide to change those values later on$.$

your code should produce $($no pun intended!$)$ a final dictionary, basket$\_$rules, that meet these conditions $($read carefully!$)$:

The values are the corresponding confidence scores, conf$(a=>b).$

Only include rules

$a=>b$ where item

Aside: Why would an analyst want to enforce Condition $3?$

Your solution can use the groceries$\_$file string variable defined above as its starting point. And since it's in the same notebook, you may, of course, reuse

any of the code you've written above as needed. Lastly, if you feel you need additional code cells, you can create them after the code cell marked for your

solution but before the code marked, ### TEST CODE ###$.$
