Script to wait till a specified time

Question

Wait till Specified Time

I need the best way to halt a program until the specified time is mentioned(in variable wait_time a tuple of hours, minutes, seconds). I had tried to use while loop for this. But is there a more efficient way for this such that it doesn't take much of the CPU. After waiting it does a function called solve().

wait_time=(12,10,15)
import time
time_str=time.localtime()
current_time=(time_str.tm_hour,time_str.tm_min,time_str,time_str.tm_sec)
while current_time!=wait_time:
    current_time=(time_str.tm_hour,time_str.tm_min,time_str,time_str.tm_sec)
else:
    print('Wait time over')
    solve()

I require a more efficient way than this for the memory part. It should wait until the system time is the time given.

Does this answer your question? [time.sleep -- sleeps thread or process?](https://stackoverflow.com/questions/92928/time-sleep-sleeps-thread-or-process) — Laurent LAPORTE, Feb 08 '20 at 17:08

I have hacked together a method that should work for you:

timeWait.py

import time

def waitTime(hrs, mins, secs):
    totalTime = ((hrs * 3600) + (mins * 60) + secs) # this is the time to wait in seconds
    time.sleep(totalTime) # time.sleep() sleeps for a given number of seconds

Using it in the shell:

Python 3.8.0 (v3.8.0:fa919fdf25, Oct 14 2019, 10:23:27) 
[Clang 6.0 (clang-600.0.57)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import timeWait 
>>> timeWait.waitTime(1, 23, 42)
# This will wait/sleep for 1 hour, 23 minutes, and 42 seconds.

How you can use it in your program:

import time

def waitTime(hrs, mins, secs):
    totalTime = ((hrs * 3600) + (mins * 60) + secs)
    time.sleep(totalTime)

waitTime(12, 10, 15)
# The following code will run when the time is up
print('Wait time over')
solve()

_`waitTime`_ sinful. – AMC Feb 08 '20 at 21:33
@AMC How so? Would you prefer ugly `wait_time`? – Captain Jack Sparrow Feb 08 '20 at 23:59
Ugly? Leave `snake_case` alone D: – AMC Feb 09 '20 at 00:07
`snake_case` is bad stuff. Everyone knows the _real_ pros use `camelCase`. Snake case is ugly, unprofessional, and hard to read. – Captain Jack Sparrow Feb 09 '20 at 00:59
I just wanted to bring up Python style conventions. – AMC Feb 09 '20 at 03:00
Well, write your code whichever way makes you feel good. _I_ personally find snake case to be new age and ugly. But that's just me. ^_^ – Captain Jack Sparrow Feb 09 '20 at 03:06

_Well, write your code whichever way makes you feel good._ Nice strawman, everyone knows conventions and standards are worthless... That’s a doubly amusing attitude coming from someone who claims to be into macs. – AMC Feb 09 '20 at 03:18
