I was wondering what would be the easiest way of executing a line at a specific time? For example, if I wanted to print a string at 3:15 PM what would be the easiest way of doing so?

You could use the sched.scheduler object from the standard library. One of its methods is enterabs() which is used to run commands at an exact time. Here is the Python page and then a page with some more examples...

https://docs.python....ml#module-sched - Scheduler (pick your version if working with 2.7.x)
http://pymotw.com/2/sched/ - More examples (check out the subtopic "Event priorities" for an example of exact time)

Hope this helps.

so I've attempted to try it out in the following way:

import sched, time

def cmd():
    os.system('shutdown -s')

scheduler.enterabs('3:00',
                   cmd())

The examples may not have been as helpful as I previously thought. Any advice?

well, you could do a

import datetime.datetime as dt
import subprocess as sub
schedtime="1551"
command=["shutdown","/s"]
if dt.now().strftime("%H%M") == schedtime: sub.call(command)

I'm using Python version 3 and I've attempted to follow that example however I get no response or error messages? Any suggestions?

from datetime import datetime
import subprocess as sub

schedtime=("14:52")

command=["shutdown","/s"]

if datetime.now().strftime("%H%M") == schedtime: sub.call(command)

...
%H%M returns the time in the form of HHMM not HH:MM, so you should use %H:%M for this, since the input has a semicolon.

Looking at the posted code, there is nothing I can see that prevents the application from terminating. In the linked scheduler page there is an example that uses sleep to keep the application alive.

I also suggest that you start by simply printing something after a brief delay (as mentioned in your first post); then attempt to print at a specific time, then finally to shutdown. That is, get the easier version(s) to work first.
