I am trying to initialize a variable as `arr = Vector{Tuple{Float64, Vector{Float64}}}()` because I will grow it with `push!`  
However, I would like to have more than that, the first type is fixed as `Float64` but I want to have more than one `Vector{Float64}` , e.g. `arr = Vector{Tuple{Float64, Vector{Float64}, Vector{Float64}}}()` .  
Is there a way to initialized my variable with N tuple elements of the same type? I don’t expect more than 5.

Answer from Slack by @mcabbott:

```julia
Tuple{Int, Tuple{(Vector{Int} for _ in 1:3)...}}` or maybe better `Tuple{Int, Tuple{ntuple(_ -> Vector{Int}, 3)...}}

```

This is what I used in the end:

```julia
N = 3
arr = Vector{Tuple{Float64, (Vector{Float64} for _ in 1:N)...}}()

```
