python 定时循环执行命令，时间判断如何写？
import time
time.localtime(time.time())
y=time.strftime("%Y",time.localtime(time.time()))
m=time.strftime("%m",time.localtime(time.time()))
d=time.strftime("%d",time.localtime(time.time()))
h=time.strftime("%H",time.localtime(time.time()))
M=time.strftime("%M",time.localtime(time.time()))
while y!=2012 or m!=12 or d!=26 or h!=9 or M!=56:
while这段为什么不行？

#1.py
from threading import Timer
from datetime import datetime
def hello():
print "Hello from ", datetime.now()
t=Timer(10,hello)
print datetime.now()
t.start()
# output

str和int比较当然不行喽
t = time.strftime('%Y-%m-%d %H:%M', time.localtime(time.time()))
转成这样再比较吧追问
t = time.strftime('%Y-%m-%d %H:%M', time.localtime(time.time()))
转成这样再比较吧追问
多给说几句呗..
追答写个死循环
from time import sleep
while 1:
if t == '2012-12-21 15:30':
print '世界末日'
break
sleep(0.1)
当时间到这个点发生世界末日，否则就sleep一下，避免占用cpu
