modify my docstring! and change the function name to find$\_$letters$()$

convert it into a function that takes a string for an argument called words

counts the number of occurrences of the letters using a dictionary data structure$(!)$

For instance $($your output look different, but the values should be the same$)$:

michael would return $\{\text{'}$i$\text{'}$:$1,\text{'}$e$\text{'}$:$1,\text{'}$a$\text{'}$:$1\}$

miguelito would return $\{\text{'}$i$\text{'}$:$2,\text{'}$e$\text{'}$:$1,\text{'}$u$\text{'}$:$1,\text{'}$o$\text{'}$:$1\}$

Printing the dictionary will be the responsibility of the caller. $($But when you are building it$,$ you can add print statements to verify your code. Good debugging technique.$)$

You make your program "case insensitive"

This means Angel should return $\{\text{'}$a$\text{'}$:$1,\text{'}$e$\text{'}$:$1\},$ not $\{\text{'}$e$\text{'}$:$1\}$

using annotations: modify the argument list to default to vowels 'aeiou', but can be changed by the caller. add the return type $(->$ set$).$

i$.$e$.,$ def find$\_$letters$($words:str$,$ letters:str$=$'aeiou'$)->$ set

which can have the following example calls

find$\_$letters$($ 'galaxy' $)$

find$\_$letters$($ 'galaxy', $\text{'}$wxyz$\text{'})$

find$\_$letters$($letters$=$'abcd', words$=$'Abba Rocks Big Time'$)$

Answer the question: Why did I use the list version, rather than the set version?

Suggested test strings $($you will have to come up with others$)-->$ miguelito, Arturo, Angelica, Chrys$,$ Senorita Bullfrog
