Getting return value From Function with loop

New to Julia

Greetings. This ius my first post. Below is code that calculates the value of a scrabble word.
It works well if I use the println() but cannot get it to return the value in total varable. Thanh you
function score(str)
letterValue = 0
total = 0

dict = Dict(‘a’ => 1, ‘e’ => 1, ‘i’ => 1, ‘o’ => 1, ‘u’ => 1, ‘l’ => 1, ‘n’ => 1,‘r’ => 1,‘s’ => 1,
‘t’ => 1,‘d’ => 2,‘g’ => 2,‘b’ => 3,‘c’ => 3,‘m’ => 3,‘p’ => 3, ‘f’ => 4,‘h’ => 4,‘v’ => 4,‘w’ => 4,
‘y’ => 4,‘k’ => 5, ‘j’ => 8, ‘x’ => 8,‘q’ => 10, ‘z’ => 10)

for character in str
letterValue = dict[character]
total += letterValue
end
end

Using Julia 1.9 and VS Code

function score(str)
    letterValue = 0
    total = 0

    dict = Dict('a' => 1, 'e' => 1, 'i' => 1, 'o' => 1, 'u' => 1, 'l' => 1, 'n' => 1, 'r' => 1, 's' => 1,
        't' => 1, 'd' => 2, 'g' => 2, 'b' => 3, 'c' => 3, 'm' => 3, 'p' => 3, 'f' => 4, 'h' => 4, 'v' => 4, 'w' => 4,
        'y' => 4, 'k' => 5, 'j' => 8, 'x' => 8, 'q' => 10, 'z' => 10)

    for character in str
        letterValue = dict[character]
        total += letterValue
    end
    total
end

Just add “total” before the last “end” as shown, and it will work.

To be a little more explicit, this is a shortcut for return total, which means that when you call the function result = score(str), the result variable will contain what you named total inside the function

THANK YOU Tried that using score(“apple”) but still no result comes out

Are you sure? Here’s a fresh REPL session:

julia> function score(str)
           letterValue = 0
           total = 0

           dict = Dict('a' => 1, 'e' => 1, 'i' => 1, 'o' => 1, 'u' => 1, 'l' => 1, 'n' => 1, 'r' => 1, 's' => 1,
               't' => 1, 'd' => 2, 'g' => 2, 'b' => 3, 'c' => 3, 'm' => 3, 'p' => 3, 'f' => 4, 'h' => 4, 'v' => 4, 'w' => 4,
               'y' => 4, 'k' => 5, 'j' => 8, 'x' => 8, 'q' => 10, 'z' => 10)

           for character in str
               letterValue = dict[character]
               total += letterValue
           end
           total
       end
score (generic function with 1 method)

julia> score("apple")
9

julia> result = score("apple")
9

julia> result
9
