Sending a keystroke to Python subprocess without stdin-PIPE -

i have windows commandline app prints output stdout , waits indefinitely keystroke end. use function handle it:

def run_command_on_windows(command):     """     run commandline program on windows os (current)     :param command: command run (string)     :return: returns result of command     """     p = subprocess.popen(['c:\\windows\\system32\\cmd.exe', '/c'] +   command.split(),                          stdout=subprocess.pipe, stderr=subprocess.pipe)     output, err = p.communicate()     p.stdin.write('\n\n')     rc = p.returncode      return output.split('\r\n') 

all easy if use 'stdin=subprocess.pipe' in popen, can't, since app crash instantly when redirect stdin that.

p.stdin.write('\n\n') 

does not work, crashed attributeerror.

is there way solve this?

write cmd script , invoke command in there i/o redirection. try echo | ... make command end.

you can try close stdin command can't wait keypress: ... < nul:

if doesn't work, write newline file , use ... < file

if doesn't work, have change source of program (it uses special code read keyboard) or kill p.terminate()
