Question

I have an exe file that I have to call with several parameters, and for this purpose I use a bat file. After I execute bat file command prompt does not close, but wait for me to press a key. Now I have to run this exe several times, and for this I want to run a script that will do it for me.

i = 0
for path in Paths
    outout = codecs.open('runExe.bat', 'w')
    output.write(PathToExe + " -param1" + " -param2 " + param2Val[0] + " -param3 " + param3Val[0] + " -param4 " + param4Val[0] + " -param5 param5Val")
    output.close()
    subprocess.call(["regsvr32.exe", path, "-u", "-s"])
    subprocess.call(["regsvr32.exe", path, "-s"])
    subprocess.call("runExe.bat")
    i + = 1

where param3Val, param4Val, param5Val are lists with values for related command prompt parameters.
When I call this bat file, everything works perfectly for the first fun of exe, but after it executes, command promt waits for my respond. When I press any key, it closes and then exe file starts with different parameters.
So I want to eliminate with key-pressing thing. I tried to put “exit” to the end of the bat file, but it did not work. How can I close command prompt window from script, when exe finishes working?
Thanks in advance!

Upd1: sarmold’s way of doing thing works fine, but I think this it is exe (console application) that is waiting for my response. Smth in exe file prevents console window from closing, but I do not have access to sources. How can I close it’s window after it executes?

Upd2: I have tried to add “shell” call after subprocess.call, but this does not seem to work either, still have to respond to the console manually 🙁

shell = win32com.client.Dispatch("WScript.Shell")
shell.AppActivate("Command Prompt")
shell.SendKeys("cls(ENTER)")

There are two possible approaches here:

1. Make only a single bat file that contains all your commands, including the regsvr32.exe commands, and execute that.

2. Have the Python script do everything for you.

For the first approach, use the "a" open mode to append to the batch file. (Perhaps delete it at script start.) Write the contents of your three commands to the batch file within the loop — so you wind up with a long batch file that includes all the commands you need.

Then call the subprocess.call() command once, outside the loop, at the end of the script, to run the entire thing.

For the second approach, remove all the batch-file writing and run your PathToExe using Python’s subprocess.call(). It’s almost as simple as deleting all lines that work with output, but change output.write() to subprocess.call() — and obviously, fiddle with the contents a little bit so they work for subprocess.call() directly.
