Given a map pets {joe:cat,mary:turtle,bill:canary} print the pet for "joe" ("cat")

python

print pets['joe']

erlang

dict:is_key(joe, Pets) andalso begin io:format("~w~n", [dict:fetch(joe, Pets)]), true end.

erlang

case dict:find(joe, Pets) of error -> false ; {ok, Pet} -> io:format("~w~n", [Pet]) end.

erlang

IsMember = ets:member(Pets, joe), if (IsMember) -> io:format("~w~n", [ets:lookup_element(Pets, joe, 2)]) ; true -> false end.

erlang

case ets:match(Pets, {joe, '$1'}) of [] -> false ; [[Pet]] -> io:format("~w~n", [Pet]) end.

erlang

case gb_trees:lookup(joe, Pets) of none -> false ; {value, Pet} -> io:format("~w~n", [Pet]) end.

clojure

(def pets '{joe cat mary turtle bill canary})

(println (get pets 'joe))

cpp C++/CLI .NET 2.0

if (pets->ContainsKey("joe")) Console::WriteLine(pets["joe"]);

cpp

cout << pets["joe"] << endl;

fsharp

if (Map.mem "joe" pets) then printfn "%s" (Map.find "joe" pets)

fsharp

if (pets |> Map.exists (fun key _ -> key = "joe")) then printfn "%s" (Map.find "joe" pets)

fsharp

let key = "joe"
match (pets |> Map.tryfind key) with
| Some(value) -> printfn "%s" value
| None -> printfn "Key %s not found" key

fsharp

if pets.ContainsKey("joe") then printfn "%s" pets.["joe"]

fsharp

if pets.ContainsKey("joe") then printfn "%s" (pets.["joe"] :?> string)
