i guess im just having a hard time creating something like
check if go condition,
else sleep
the double while loops take 12% cpu usage on my machine so this is
probably unacceptable.
also the sleep command does not like me :
>>> from datetime import *
>>> from time import strftime,localtime,sleep
>>> time.sleep(3)
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
time.sleep(3)
AttributeError: type object 'datetime.time' has no attribute 'sleep'
>>>
here it is updated with the hour/min check fixed.
#updated python code
import os,string,time,getpass,md5,ConfigParser
from datetime import *
from os.path import join, getsize
from time import strftime,localtime,sleep
config = ConfigParser.ConfigParser()
config.read("config.ini")
date = config.get("myvars", "date")
time = config.get("myvars", "time")
while datetime.now().weekday() == int(date):
str_time=strftime("%H:%M",localtime())
while str_time == time:
print "do it"
