What is julia magic explain with example

This recipe explains what is julia magic explain with example

Recipe Objective

This recipe explains what julia.magic in Julia.

Julia.magic

We can directly execute Julia code using %julia magic in IPython. For more complex expressions We can call Python code from inside of %julia blocks via $var for accessing single variables or py"...". Code inside %julia blocks obeys the Python scope. Inside a string or block $var and py"..." retain their usual Julia behavior instead of calling python.

%load_ext julia.magic
%julia [9 8; 7 6] .+ 9
a = [9, 8, 7]
%julia $a .+ 9
%julia sum(py"[y**3 for y in a]")
g = "Python" %julia
g = "Julia"
%julia ("this is $g", "this is $($g)")
%julia @eval $g
%julia typeof(py"1"), typeof(py"1"o)
z = "Global"
def func():
z = "Gocal"
r = %julia py"z"
return r
func()
