must be obvious, but I have tried many

```julia
julia> d = Dict("One" => 1, "Two" => 2, "Three" => 3); String(keys(d))
ERROR: MethodError: Cannot `convert` an object of type Base.KeyIterator{Dict{String,Int64}} to an object of type String
This may have arisen from a call to the constructor String(...),
since type constructors fall back to convert methods.

```

I have tried many variations, using convert, etc.

Maybe you want `collect(keys(d))`?

thanks, steward, but not enough. I would like to understand how to convert this from substrings to strings. the following is an example, not to get a solution, but to illustrate the difference. I want to just get a simple one-dimensional string array out of split.

```julia
julia> mystring="a ab ac ab ab ad ba"
"a ab ac ab ab ad ba"

julia> wordcounts= Dict{String,Int64}; \
       for word in collect(split(mystring)); wordcounts[word]= get(wordcounts, word, 0) + 1; end
ERROR: MethodError: no method matching get(::Type{Dict{String,Int64}}, ::SubString{String}, ::Int64)
Closest candidates are:
  get(::ObjectIdDict, ::ANY, ::ANY) at associative.jl:434
  get(::Base.EnvHash, ::AbstractString, ::Any) at env.jl:79
  get(::Dict{K,V}, ::Any, ::Any) where {K, V} at dict.jl:478
  ...

It works, just do `wordcounts = Dict{String,Int}()` to actually create a dict object rather than referring to the type itself. You don’t even need to call `collect`.

In general it’s a good idea to provide a reproducible example, as it makes it clear what you want to do, and what might be the problem.

thanks. this was very helpful for my specific example, but let’s say I am not only stupid but also stubborn, and I really want to know how to convert the type of split(mystring) from an `Array{Substring{String},1})` into an `Array(String,1)`. How would I do this?

`String.(split(mystring))`
