I have this notebook:

arg1 = "input.txt";
arg2 = "output.txt";
u1 = Import[arg1, "Table"];
u2 = u1(*extremely complicated and long chain of operations*);
Export[arg2, u2]

and I would like to run it in a Python program like this:

def run(arg1,arg2):

for i in range(100):
    run("input{}".format(i), "output{}".format(i))

How can I do this? Preferably without GUI and several threads in parallel (I can use 4 cores in Mathematica).

  • $\begingroup$ Why not open a connection to a kernel with subprocess.Popen? Then you can communicate with that via pipes. $\endgroup$ – b3m2a1 Mar 20 '18 at 4:06
