Hi there,
I am writing a batch file in Python. The batch file, in part, calls a program named "oq-console.bat" to run. Then once the program comes up (it looks like windows CMD), I need the batch file to type some commands to make it run (just like I would do it by myself).
I need the batch file does the whole things automatically, I mean calls the program, types in commands and press enter!
So far, I have used the below Python codes in my batch file to do that;
import subprocess
subprocess.call(["C:\Program Files (x86)\OpenQuake Engine\oq-console.bat", "oq --run", "job.ini"])
Note that the first string is the program, and the last two are the commands which needs to be typed in.
It pulls up the program well, but doesn't type in the commands to make it to run.
Any ideas on how I can get the program to run the commands as well?
Thank you!

Try using the stdin argument of subprocess.

The program doesn't ask for more input parameters as all parameters are in input files and the program will automatically read the files, but I need to type in some required commands and press enter.

think what you mean is that it *is* interactive, at least requiring some

input before it begins to work.
As the other person who replied said, it sounds like this program will
accept input on standard in. From python you will probably have to use
subprocess.popen and use the .communicate() method. You will be able to
pass in a string that will get fed to the subprocess on it's standard in
pipe (the equivalent of typing and pressing enter). Check the online
docs, particularly for the .communicate() method.

If you need to start up a program, provide interactive input to it, and

perhaps examine its interactive output, then you want the "pexpect" module:
Pexpect is a pure Python module for spawning child applications;
controlling them; and responding to expected patterns in their output.
Pexpect allows your script to spawn a child application and control it
as if a human were typing commands.

Does Pexpect work on Windows?

In the OP's case it looks like the standard in pipe is sufficient.

This might be totally irrelevant, but, if (a) the data to be read by the
program during a given run is known when the program is run/launched, (b)
that data is purely textual and (c) that data can be read by the program
from the stdin channel, then my idea is (1) before the launch, put that
data into a file named, say, inputfile.dat, and then (2) launch the
program with a command like
call program.bat <inputfile.dat
Moreover, if the program needs to output textual data, and can do so using
stdout, then the data can be sent to another file named, say,
outputfile.dat as follows:
call program.bat <inputfile.dat >outputfile.dat
Finally, if the program can read its data from a given file and possibly
needs to output its data, again, to a named file, and those files' names
can be read from the parameters to the call, then
call program.bat inputfile.dat outputfile.dat
can be used.
