BlockPy: #$22\mathrm{.}3)$ Calling Inside Definitions

The function combine$\_$message below will consume three messages and combine them into one. It is supposed to use the improve$\_$message to also improve the messages before returning them. Fix the body of the combine$\_$message function so that it correctly calls the improve$\_$message function.

from cisc$108$ import assert$\_$equal

def improve$\_$message$($a$\_$string: str$)->$ str:

return a$\_$string.replace$(\text{'}$dog$\text{'},$ 'doggo'$)$

def combine$\_$messages$($first: str$,$ second: str$,$ third: str$)->$ str:

return first $+\text{'}$

$\text{'}+$ second $+\text{'}$

$\text{'}+$ third

first $=$ 'That dog is cute.$\text{'}$

second $=$ "I want to pet the dog."

third $=$ "I will ask the dog's owner."

assert$\_$equal$($combine$\_$messages$($first$,$ second, third$),$

$("$That doggo is cute.

$"+$

"I want to pet the doggo.

$"+$

"I will ask the doggo's owner."$))$
