python自动获取多个安卓adb设备名

import os

def check_adb_devices():
    '''
    检查adb 设备，并返回设备sn list
    
    :return: 设备sn list
    '''
    adb_list=[]
    ret =os.popen('adb devices').readlines()
    print('ret={}'.format(ret))
    if len(ret) ==1:
        print('未识别到adb 设备...')
        return adb_list
    else:
        for n in ret:
            if 'tdevicen' in n:
                adb=str(n).strip().split('tdevice')[0].strip()
                adb_list.append(str(adb))

        print('adb设备数量={}，adb_list={}'.format(len(adb_list), adb_list))
        return adb_list


if __name__ == '__main__':
    check_adb_devices()

执行结果：

ret=['List of devices attachedn', '1234a4f3tdevicen', 'mn4xwsbfrdtdevicen', 'n']
adb设备数量=2，adb_list=['1234a4f3', 'mn4xwsbfrd']
