Execute Julia file from Python script

Question

I'm trying to develop a Python script to deploy on AWS Lambda that will handle an invocation, prep data, and then pass that data input into a Julia script for processing (I am looking at Julia to speed up execution time compared to Pandas). I have been working with the PyJulia library locally to try and get a simple test example but running into issues. What are the issues with this set-up?

Here is the simple Python code:

python_handler.py

from julia import core.Julia

x = Julia()
print(x.eval("julia_script.jl"))

Here is the Julia script to be called:

julia_script.jl

for i in 1:10
    println(i)
end

From running 'python python_handler.py" I am expecting the julia_script.jl file to run printing 1-10 in the console but I keep getting errors.

Here's the repo importing from: https://github.com/JuliaPy/pyjulia/blob/master/src/julia/core.py

Is this even possible with Python and Julia, and if so, am I calling it the right way.

I believe you mean to do x.eval('include("julia_script.jl")')

eval behaves basically like the REPL
