[julia-users] Re: How to built an array with some keys of a dictionary ?

Hi Steven,


I also tried  a = Array{String}() unfortunately it produces errors as well.



julia> a = Array{String}()
WARNING: Base.String is deprecated, use AbstractString instead.
  likely near no file:0
0-dimensional Array{AbstractString,0}:
#undef


julia> for k in keys(dict)
         if dict[k] < 2
           continue
         end
           push!(a, k)
       end
ERROR: MethodError: `push!` has no method matching push!(::Array{
AbstractString,0}, ::ASCIIString)
Closest candidates are:
  push!(::Any, ::Any, ::Any)
  push!(::Any, ::Any, ::Any, ::Any...)
  push!(::Array{Any,1}, ::ANY)
