Python限制内存和CPU使用量的方法（Unix系统适用）

import signal
import resource
import os

def time_exceeded(signo, frame):
 print("Time's up!")
 raise SystemExit(1)

def set_max_runtime(seconds):
 # Install the signal handler and set a resource limit
 soft, hard = resource.getrlimit(resource.RLIMIT_CPU)
 resource.setrlimit(resource.RLIMIT_CPU, (seconds, hard))
 signal.signal(signal.SIGXCPU, time_exceeded)

if __name__ == '__main__':
 set_max_runtime(15)
 while True:
  pass

import resource

def limit_memory(maxsize):
 soft, hard = resource.getrlimit(resource.RLIMIT_AS)
 resource.setrlimit(resource.RLIMIT_AS, (maxsize, hard))
