让chatgpt达芬奇帮忙写代码

问：

帮我写一段python脚本，要求注册信号，当接收到信号值15后，程序正常退出

答：

import signal
import sys

def signal_handler(signal_num, frame):
	if signal_num == 15:
		print("Received signal: %s, program exits normally" % signal_num)
		sys.exit()

# register signal
signal.signal(15, signal_handler)

print("Waiting for signal 15...")
while True:
	pass

这跑起来稳稳的。。。
