Hi! I am new to julia and I am trying to use julia in python because i need some python libraries.  
I have some julia function that i would like to call using juliacall, but I got stuck when `[]` was called on a zero-dimensional array and I don’t know how to do the same with juliacall, because it gives me syntax error.  
Just to be precise: I have a short julia code `f(...)[]` where the function f returns a zero-dimensional array. With juliacall I am calling jl.library\_containg\_the\_function.f(…) and it works, but i don’t know how to use `[]`.  
Furthermore, I would like to not modify anything in the julia library.

Welcome. Indexing with square brackets is the syntax for calling the [`getindex`](https://docs.julialang.org/en/v1/base/arrays/#Base.getindex-Tuple%7BAbstractArray,%20Vararg%7BAny%7D%7D) function. So you can replace `x[]` with `getindex(x)`, both in Julia itself and in juliacall.

You can also do `x[()]` in Python.

Why? Well `x[a,b,c]` is just shorthand for `x[(a,b,c)]`, i.e. indexing with a single tuple. This means that Python objects supporting “multi-indexing” actually just check if the given index is a tuple. Therefore you can do “empty-indexing” with the empty tuple.
