from subprocess import Popen,PIPE,STDOUT
a=Popen('parted -s',stdout = PIPE, stderr = STDOUT, shell = True)
a.communicate(input="print".encode())
string=a.stdout.read()

您可以在不向儿童的标准输入发送输入的情况下实现此目的,只需使用命令行并使用subprocess.check_output()
执行:
import shlex
import subprocess
DEVICE = '/dev/sda'
cmd = 'parted -s {} print'.format(DEVICE)
output = subprocess.check_output(shlex.split(cmd))
>>> print output
