In python,

```julia
args ={"a":2 ,"c":1,"e":9}

def test(a,c,e):
   print(a,c,e)

test(**args)

```

My I know the similar way of passing arguments in Julia? Thanks

Here is one way:

```julia
test(a,c,e) = println("$a $c $e")

args = (2,1,9)

test(args...)

```

aslo

```julia
test(;a=0,c=0,e=0) = println("$a $c $e")

args = Dict(:a=>2, :c=>1, :e=>9)

test(;args...)

```

test (generic function with 1 method)

julia> test(;args...)

That rather corresponds to `test(*args)` in Python.

This may lead to unexpected results:

```julia

julia> test(a, c, e) = println("$a $c $e")
test (generic function with 1 method)

julia> args1 = (a=2, c=1, e=9)
(a = 2, c = 1, e = 9)

julia> test(args1...)
2 1 9

julia> args2 = (a=2, e=9, c=1)
(a = 2, e = 9, c = 1)

julia> test(args2...)
2 9 1

```

Edit: @GunnarFarneback is correct. This inconsistency is only because I did not use `;` specifying keyword arguments.

Yeah, was way too quick. I’ve edited out that misinformation.
