A sample dataset has been provided to you in the $\text{'}./$data$/$dataset$.$pickle' path. Here are the attributes for the dataset. Use this dataset to test your functions.

Dataset should load the transactions in the form of a python dictionary where each key holds the transaction id and the value is a python list of the items purchased in that transaction.

An example transaction will have the following structure. If items A$,$ C$,$ D$,$ F are purchased in transaction T$3,$ this would appear as follows in the dictionary.

transactions $=\{$

$"$T$3"$: $["$A$","$C$","$D$","$F$"]$
