[julia-users] Re: Possible to use filter! on a child dict within a parent dict, to remove the entire parent dict if condition in child is met?

[Jeffrey Sarnoff]

if you want to do this, yes:


julia> a=Dict("A"=>1, "B"=>2)
Dict{ASCIIString,Int64} with 2 entries:
  "B" => 2
  "A" => 1

julia> around_a=Dict("A"=>3, "B"=>a)
Dict{ASCIIString,Any} with 2 entries:
  "B" => Dict("B"=>2,"A"=>1)
  "A" => 3

julia> if (around_a["B"]["A"] == 1) 
          delete!(around_a["B"],"A");
       end

julia> around_a
Dict{ASCIIString,Any} with 2 entries:
  "B" => Dict("B"=>2)
  "A" => 3
