7def handler(signum, frame):
8  print("Forever is over!")
9       raise Exception("end of time")
10   
11
12# This function *may* run for an indetermined time...
13def loop_forever():
14     import time
15     while 1:
16         print("sec")
17         time.sleep(1)
18         
19

21# Register the signal function handler
22signal.signal(signal.SIGALRM, handler)

25# Define a timeout for your function
26signal.alarm(10)
