最近,我对Python语言感兴趣,所以我尝试测试以下内容 码。

import sched
import time

scheduler = sched.scheduler(time.time, time.sleep)

def print_event(name, start):
    now = time.time()
    elapsed = int(now - start)
    print 'EVENT: %s elapsed=%s name=%s' % (time.ctime(now), elapsed, name)

start = time.time()
print 'START:', time.ctime(start)
scheduler.enter(2, 1, print_event, ('first', start))
scheduler.enter(3, 1, print_event, ('second', start))

scheduler.run()

测试后我得到如下错误:

calvin @calvin-K42Jv:/ usr / local / myprjs / Python $ python sched3.py Traceback(最近一次调用最后一次):   文件" sched3.py",第1行,in     导入sched   文件" /usr/local/myprjs/Python/sched.py" ;,第2行,在     s = sched.scheduler(time.time,time.sleep) AttributeError:'模块'对象没有属性' scheduler'
