You need to test if ask is equal to 'yes'
Testing 'yes' directly will always be true because 'yes' always exists.

and use that stored value in the test.

"You also need to write a function "printList" of one parameter that
takes a list as its input and neatly prints the entire contents of the
list in a column."
