How to take user input and insert it into an array?

Question

New to Julia, trying to simply ask the user to choose 5 numbers and put it into an array and print the array. My output only says pick 5 numbers with "nothing" followed underneath. I cant seem to figure out why it wont read my inputs.

function ask()
   lst = []
   i = 0
   println("pick 5 numbers to add to a list")
   while i < 5
     choice = readline
     choice = push!(lst, choice);
     i += 1
    end 
end
 
println(ask())

Answer 1

You were assigning function reference to list elements rather than calling the function.

This should be:

function ask()
   lst = String[]
   i = 0
   println("pick 5 numbers to add to a list")
   while i < 5
     choice = readline()
     choice = push!(lst, choice);
     i += 1
   end 
   lst
end

If you want numbers rather than Strings the last line could be parse.(Int, lst) or you could add this conversion near readline

Note that if you do not plan to introduce some error checking etc. this all code could be simply written as:

println("pick 5 numbers to add to a list")
lst = [parse(Int, readline()) for _ in 1:5]
