Better Way to Monitor Time Request. - bill_z - Oct-16-2020
Being new to Python, but not to programming, I’m concerned with efficiency regarding CPU cycles. My project is to collect data then write it out to a log file every 5 minutes. I want to write nearly exactly every 5 minutes by the clock. I really want it to report on the hour and exactly every 5 minutes after. Python on a Raspberry Pi 3B+
The following sample code does work but I’m betting there is a more efficient way to do this. Us new guys don't know many tricks.
Will someone suggest a better way please?
import time, datetime
from time import sleep
last = 0
try:
while True:
date_time = datetime.datetime.now()
date = date_time.date() # Gives the date
time = date_time.time() # Gives the time
min = int(time.minute) # Gives the minute
if min != last:
if min in (00,05,10,15,20,25,30,35,40,45,50,55):
print ("time :",date, time)
last = min
except KeyboardInterrupt:
print('You canceled the operation.')

I would try to use the builtin sched module for this.

You could also use cron (I'm assuming Raspbian has a cron daemon running by default of course) to run your program at the scheduled times.
