Hi All,

I have an executable file (main.exe) which reads user-input from input.ini and also uses the other files below.

In MATLAB's command prompt, I run the executable like this

!main

I am not sure how to run this file from Python.

Suggestions will be of great help.

Hi @Torsten,

I tried,

exe_str = r"C:/Windows/System32/cmd I:/sim/main/main.exe"
process = subprocess.Popen(exe_str, stderr=subprocess.PIPE, creationflags=0x08000000)
process.wait()

but the output file has not been saved to the output folder. There is no issue while running the !main i.e output file is created.

Try it like this:

import subprocess
exe_str = "I:/sim/main/main.exe"
result = subprocess.run(exe_str, capture_output=True, text=True)
print("STDOUT=", result.stdout)  # optional
print("STDERR=", result.stderr)  # optional
