使用subprocess庫(kù)：try:
p = subprocess.Popen(["ping", "-c", "5", "www.bing.com"], stdout=subprocess.PIPE)
p.wait()
except KeyboardInterrupt as e:
p.terminate()或者使用sh庫(kù)：try:
p = sh.ping("-c", "5", "www.bing.com", _bg=True, _bg_exc=False,
_out=sys.stdout, _err=sys.stderr)
p.wait()
except KeyboardInterrupt as e:
alive, _ = p.process.is_alive()
if alive:
p.process.terminate()這種結(jié)束外部進(jìn)程的方式有什么缺點(diǎn)？
使用python調(diào)用外部程序產(chǎn)生進(jìn)程，優(yōu)雅關(guān)閉的最佳實(shí)踐是什么？
