在Python中处理超时异常

import signal

class TimeoutError(Exception):
    pass

def handler(signum, frame):
    raise TimeoutError("Operation timed out")

def do_something():
    # 执行某个操作

# 设置超时时间为5秒
signal.signal(signal.SIGALRM, handler)
signal.alarm(5)

try:
    do_something()
except TimeoutError:
    print("Operation timed out")
finally:
    signal.alarm(0)  # 取消超时设置

import threading

class TimeoutError(Exception):
    pass

def do_something():
    # 执行某个操作

def timeout_func():
    raise TimeoutError("Operation timed out")

# 设置超时时间为5秒
timeout = 5

t = threading.Thread(target=do_something)
t.start()
t.join(timeout)

if t.is_alive():
    # 超时处理
    timeout_func()
