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

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.
