From Python to Mathematica and back again

python shell import export wolfram-mathematica

On way to do this:

Put your Mathematica code into a plain text file for example make_arr.m
Use command line interface of Mathematica:
- math -script make_arr.m
From python invoke the above with the subprocess module
- subprocess.call(["math", "-script", "make_arr.m"])

Optionally you can use command line arguments in the Mathematica script:

file_name = $CommandLine[[4]]
