Functions Exercise $3$ in python

Problem

Write a function called search$\_$list that takes a list and a search term as parameters. If the search term is located in the list, return the index of the matching element. The function should work even if there is a difference in capitalization. If the search term is not in the list, return $-1.$

Expected Output

If the function call is search$\_$list$(["$dog$",$ "fish", "cat"$],$ "Cat"$),$ the the function would return $2$

If the function call is search$\_$list$(["$water$",$ "Toy", "house"$],$ "toy"$),$ then the function would return $1$

If the function call is search$\_$list$(["$box$",$ "car", "hat"$],$ "mouse"$),$ the the function would return $-1$
