Python子进程中的按键？

Question

try:
    subprocess.run(exe_path)
    keyboard.press_and_release('enter')
    print('Successful Extracted')
except Exception as exe:
    print(exe.args)
    keyboard.press_and_release('enter')

The point is to run the EXE of windows but it needs input of keyboard to end it's process, and it will remain stuck over there unless a keyboard input given physically. Right now i am facing issue as

subprocess.run('some_exe')

is running the process and after successfully run asking

Press Any Key To Exit

while i have already mentioned next to subprocess.run

keyboard.press_and_release('enter')

and it's coming to next line unless we press the button from keyboard manually

NOTE: python3.8

Answer 1

You can create a .vbs file to run your .exe file or python script without console debugging window:

Set oShell = CreateObject ("Wscript.Shell") 
Dim strArgs
strArgs = "cmd /c  python main.py"
oShell.Run strArgs, 0, false

If you have .exe file just replace python main.py with yourFile.exe .

Answer 2

For the sake of a reproducible example, say we want to run the following Python script as a subprocess, let's call it script.py .

input('Press Enter to exit.')

It won't terminate until the user presses the Enter key. If we want to emulate the key press, we can just send a newline character to the subprocess's stdin using Popen.communicate . Like so:

from subprocess import Popen, PIPE

process = Popen(['python', 'script.py'], stdin=PIPE, text=True)
process.communicate('\n')

Obviously this also works if the external program accepts any key to exit. Only sending special keys which don't have an obvious text representation, such as F1 , would complicate things.
