Question

我尝试使用子进程模块和win32，但是它没有满足我的要求，因为SendKeys仅在脚本执行过程中不执行任何活动时才起作用

我需要先将adb设备连接到PC，然后通过为每个设备启动命令提示符将“ adb reboot bootloader”命令传递给每个设备

我可以在这方面获得帮助吗？

        #window = GetForegroundWindow()

    f.close()
    print devices_list[2]
    #new_device = str(devices_list[2])
    #print(new_device.strip("',[,',]"))

    command2 = "adb -s "+ str(devices_list[2]).strip("',[,',]") + " reboot bootloader {ENTER}"
    run_venv.open_cmd(shell)
    #run_venv.run_py_script(shell, command2)

使用subprocess.Popen：

from subprocess import Popen, PIPE
p1 = Popen(['cat'], stdin=PIPE, stdout=PIPE)
p2 = Popen(['cat'], stdin=PIPE, stdout=PIPE)
p1.stdin.write(b'hello1\n')
p1.stdin.flush()
print('p1:%s' % p1.stdout.readline())
p2.stdin.write(b'hello2\n')
p2.stdin.flush()
print('p2:%s' % p2.stdout.readline())
p1.stdin.write(b'world1\n')
p1.stdin.flush()
print('p1:%s' % p1.stdout.readline())
p2.stdin.write(b'world2\n')
p2.stdin.flush()
print('p2:%s' % p2.stdout.readline())

这将输出：

p1:hello1
p2:hello2
p1:world1
p2:world2

如何在python中将不同的命令发送到两个不同的cmd窗口
