Can someone help me with the following please: I am new to clojure and i
haven't developed in 4 years, previous was mainframe. See questions in blue
; Task is to add full state name based on st_abbr
(def input-file [{:st_abbrev "AZ", :firstname "john", :lastname "smith"}
{:st_abbrev "FL", :firstname "roy", :lastname "wills"}
{:st_abbrev "OH", :firstname "jay", :lastname
"louis"}])
*Question 1: How do I make these between the lines into one Defn?*
-----------------------------------------------------------------------
(def get-state
(#(map :st_abbrev input-file)))
#'user/get-state
("AZ" "FL" "OH")
(defn state-desc [get-state input-file]
(let [desc get-state]
(case desc
"AZ" (assoc input-file :state "Arizona")
"FL" (assoc input-file :state "Florida")
"OH" (assoc input-file :state "Ohio")
"default"
)))
(map state-desc get-state input-file)
#'user/state-desc
({:st_abbrev "AZ", :firstname "john", :lastname "smith", :state "Arizona"}
{:st_abbrev "FL", :firstname "roy", :lastname "wills", :state "Florida"}
{:st_abbrev "OH", :firstname "ja y", :lastname "louis", :state "Ohio"})
---------------------------------------------------------------------------
Question 2: I tried to combine in one defn, but it's not working, any help
would be appreciated
(defn state-desc2 [input-file]
(let [desc2 (#(map :st_abbrev input-file))]
(case desc2
"AZ" (assoc input-file :state "Arizona")
"FL" (assoc input-file :state "Florida")
"OH" (assoc input-file :state "Ohio")
"default"
)))
(map state-desc2 input-file)
#'user/state-desc2
("default" "default" "default")
