Juliacall access zero-dimensional array with []

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 function. So you can replace x[] with getindex(x), both in Julia itself and in juliacall.


Thank you so much for the reply! It solved my problem :slight_smile:

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.
