Enumerate with keys from a dict

New to Julia

I am wondering if the behaviour in the picture below is intended? Shouldn’t i stop at 9999?

I cannot reproduce:

julia> d = Dict((i=>i for i=1:9999));

julia> for (i,v) in enumerate(keys(d))
       if i==10000
       @show i
       end
       end

Can you provide a MWE? (And please use text and not pics as those cannot be copy pasted)

Thanks for the fast reply! I guess it might be because I am using Threads.@threads beforehand.

succeded = Dict{Int,Any}()
Threads.@threads for i = 1:1000
   succeded[i] = ["a"]
end
length(keys(succeded)) # returns 806

Does that make sense?

The problem here is that Dict is not thread safe and you are therefore creating race conditions. You might be interested in this thread:
