Don;t use eval() its bad practicecand fort advanced use only.
Instead explicitly convert to int() or float()

Same here.

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

you need to store the reurn value from input as you did above

and use that stored value in the test.

Thank you I finally fixed it. Can anyone break down how to do the next step which is:

"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."
