Mapping a boolean to a list in clojure

I am trying to get a list to evaluate to a true/false against a particular number. When I define the function, clojure defines it fine. But it is not doing what I want to do. Just learning clojure... so I am not very comfortable with the syntax yet... apologies if this is a noob question.

Ideally it would take in a list like (list 9 0 3) and evaluate it to (list true false true)

(defn myfunc [lst](map (> x 1) lst))

Here is the correct syntax:

(defn greater-than-one?
  [x]
  (< 1 x))

and then use it:

(mapv greater-than-one? (list 9 0 3)) => [true false true]

In your original format, you could also solve it like:

(defn myfunc [lst]
  (map #(> % 1) lst))

and use it:

(myfunc (list 9 0 3)) => (true false true)

You may find this template project helpful in getting started. Please be sure to see the list of documentation also.
