How to import two inputs in sequence for subprocess.Popen

Question

The .exe requires two input in sequence such as:

what is your input 1: File1
what is your input 2: File2

Then it will run. I am trying to use

p = subprocess.Popen([.exe, File1], cwd=filename_dir, stdin=subprocess.PIPE, stdout=subprocess.PIPE)
time.sleep(1)
p.communicate(input=File2)

and it does not work, any help?

I think you need to manipulate the `stdin` instead of trying to pass the file names as parameters. — BurningKarl, Jun 21 '17 at 16:09

m=p.communicate(input=b'filename1\nfilename2\n')[0]
