Just use kill

os.system has very weak control, you need the .kill method of the subprocess module to send signals.

But if it’s just ping, why don’t you just let it ping 10 times? What do you want to do?

I don’t know if I can meet your needs

The main problem is that the executed command never returns, os.system cannot determine whether the command has been executed and executed successfully
If you can try a simple cmd command
os.system('start ping www.baidu.com -t')

Registersignal.SIGINTSignal

I tried it, and I can probably write it like this:

import time

start = end = time.time()
def re(cmd):
    while (end - start) < 10:
        os.system(cmd);
        end = time.time()
