I have a function  
**function inputs(setup::Dict, path::AbstractString)**

What actually setup meaning here ? Is it like input::Dict ?

The name doesn’t have any meaning. It’s just a variable name that you can use inside the function. You can call it `setup`, `input`, `x`, `strawberry_jam` or whatever you want.

The `::Dict` part means that `setup` (or whatever you want to call it) must some subtype of `Dict`.

Have you read

[https://docs.julialang.org/en/v1/manual/functions/](https://docs.julialang.org/en/v1/manual/functions/)

and

[https://docs.julialang.org/en/v1/manual/methods/#Methods](https://docs.julialang.org/en/v1/manual/methods/#Methods)

?

The manual provides a very detailed explanation on both points made by @DNF above.
