I have an exe-file that I need to run several times with different parameters. I can manually (or with Python) create a bat-file with all the parameters and then run the exe-file C:\RAY\Reflec.exe < test.bat in a cmd window but I run into problems when I try to make Python run it. The exe-file is executed but it does not take in the parameters in the bat-file. I have tried various ways, e.g. using os.startfile, subprocess.call, and so on but I can not get it to work.
