我这里用到了subprocess.Popen()和subprocess.run()  
执行ping命令示例如下：

# -*- coding: utf-8 -*-
    import os
    import subprocess
    import re
    import sys
    
    
    def get_ping(ip, count):
        platform = sys.platform
    
        if "win" in platform:
        	command = 'ping -n %s' % count + " %s" % ip
            p = subprocess.Popen(command,
                                 stdin=subprocess.PIPE,
                                 stdout=subprocess.PIPE,
                                 stderr=subprocess.PIPE, shell=True)
            out = p.stdout.read().decode('gbk')
            # regex = r'时间=(.+?)ms'
    
        elif "linux" in platform:
        	command = 'ping -c %s' % count + " %s" % ip
            p = subprocess.Popen([command],
                                 stdin=subprocess.PIPE,
                                 stdout=subprocess.PIPE,
                                 stderr=subprocess.PIPE, shell=True)
            out = p.stdout.read().decode('utf-8')
            # regex = r'time=(.+?)ms'
    
        print(out)
        
    
    
    if __name__ == '__main__':
        ip = 'www.baidu.com'
        count = 4
        command = 'ping -n %s' % count + " %s" % ip
        print(command)
        
        proc = subprocess.run(command, shell=True, stdout=subprocess.PIPE)
        print(proc.stdout.decode("gbk"))
    
        # p = subprocess.Popen(['D:', 'cd /home/dev/train_work/ymtcv/', './start_train.sh', 'terminal', '10'], stdout=subprocess.PIPE, shell=True)
    
        print('1==========================================1')
    
        p = subprocess.Popen(command, stdout=subprocess.PIPE, shell=True)
        print(p.stdout.read().decode("gbk"))
    
        print('2==========================================2')
    
        get_ping('www.baidu.com' , 4)
    
        print('3==========================================3')
