Python calls the ADB command to implement reboot for multiple devices at the same time

First, ADB's reboot command for devices is: ADB reboot. However, if it is two/more devices, you need to declare serial number:adb-s Serial_no reboot.

So how do you use Python to implement ADB operations on multiple devices (reboot)?

This involves the use of the Python subprocess model:

Import subprocess

ADB device gets serial number for all devices:

devices = subprocess. Popen (
    ' adb devices '. Split (),
    stdout=subprocess. PIPE,
    stderr=subprocess. PIPE
). Communicate () [0]

So the return information for the ADB device command is under devices, but we only need serial number:

Serial_nos = [] for
the item in Devices.split ():
    filters = [' list ', ' of ', ' device ', ' devices ', ' attached ']
    if Item . Lower () Not in filters:
        serial_nos.append (item)

So the Serial_nos save is all the serial number of the device, we only need to adb-s it in turn [Serial_number] reboot:

For Serial_no in Serial_nos:
    reboot_cmds.append (' adb-s%s reboot '% serial_no) for
Reboot_cmd in Reboot_cmds:
  subprocess. Popen (
        reboot_cmd.split (),
        stdout=subprocess. PIPE,
        stderr=subprocess. PIPE
    ). Communicate () [0]

In this way, each device has a reboot operation ...
