Not sure where i went wrong on this defintion. Need help

We are now ready to write the definition of the type$\_$bonus function, which will calculate the type bonus of an attack$\_$type against a defender. We have provided a code snippet for you to work with. You may rewrite the entire function from scratch if you want to$.$

$19]$: def type$\_$bonus$($attack$\_$type, defender$)$:

# TODO: store the 'type$1\text{'}$ and 'type$2\text{'}$ of the 'defender' in variables

# 'defender$\_$type$1\text{'}$ and 'defender$\_$type$2\text{'}$

# TODO: replace the $...$ with your code

defender$\_$type$1=$ defender.type $1$

defender$\_$type $2=$ defender.type $2$

if defender$\_$type$2$:

bonus $=$ project.get$\_$type$\_$effectiveness$($attack$\_$type, defender$\_$type$1)$

return bonus

else:

bonus $=$ project.get$\_$type$\_$effectiveness$($attack$\_$type, defender$\_$type$2)$

return bonus
