Hi all … I still do not understand well …

This works:

```julia
println("2° dictionary")
myDictionary2 = Dict{String,Vector{Int64}}
myDictionary2("betha"=>[1,2,3,4,5])

```

This other doesn’t:

```julia
println("3° dictionary")
myDictionary3 = Dict{String,Vector{Int64}}
push!(myDictionary3,"alpha"=>[10,20])     

```

How exactly should be the last line, using push! ? or is myDictionary3 = … that i have to change in another way, to have an instance and not a type ?

Many thanks 🙂
