I have written a script to read and write in excel.
Now looking to run this script in every 15 minutes periodically.
Is there any one who can modify the code with time scheduler.
Here is the script:

If you're on a *nix based operating system you can use cronjob. On windows you'd want to use a scheduled task.
To setup the cronjob it would be something like:
crontab -e
Edit this file to include the call to your script:
*/15 * * python /home/useraccount/dev/yourpythonscript.py
This will make run every 15 minutes, every hour, every day, every month.
You can use the module time module.
Use function time.sleep (<seconds>)
Check this out.

I want to be able to run my python script which scans for something related to cryptocurrencies 1 minute after the same script has just been complete. Is this possible? Or could I maybe set a limit before the loop repeats itself or something?
The code I have isn't something I am willing to share due to its sensitive nature. It is a trading bot.
You have a few solutions:
Use a cron job if you are on a unix like platform (you can use this for the syntax, or man cron in the terminal to learn more about it)
Create a long running python script that sleeps for one minute before executing your logic again. Something like this:
import time
while True:
# execute code here
time.sleep(60)
If you are running it on Windows platform ,
You can create a batch file to run your script in cmd using the following command:
start "" "path_to_python.exe" "path_to_python_script"
then create a task in windows task scheduler .

I am working on a Python program. It needs to run every 15 minutes. It currently waits 870 seconds (14.5 mins) before running again, but as the time it takes to complete the action varies, sometimes it runs before it has been 15 minutes since it last run, sometimes after 15 minutes.
My code for this part currently looks like this:
print(colour.BOLD, colour.PURPLE, "Finished", colour.END)
print(colour.BOLD, colour.BLUE, 'WAITING 15 MINUTES (900 SECONDS)', colour.END)
time.sleep(870)
Is there a way I can get it to run at xx:15, xx:30, xx:45, xx:00 where xx is every hour from 00 to 23?
Sorry if I'm being confusing here. Thanks for any help in advance.
I would use the schedule module: https://pypi.org/project/schedule/
you would run:
schedule.every().minute.at(":00").do(job)
schedule.every().minute.at(":15").do(job)
schedule.every().minute.at(":30").do(job)
schedule.every().minute.at(":45").do(job)
Use your OS tools to achieve similar results.
They are very reliable and, in case of your script failure, it will run anyway next time.
Linux
Use crontab.
How to set it will slightly change depending on your Distribution.
As a general idea:
sudo crontab -e
Inside the crontab write (be sure to customize the python executable and script path):
*/15 * * * * /usr/bin/python /path/to/your/script.py
This will make sure that your script is executed every 15 minutes.
Windows
How to schedule a task on Windows is more dependent on the Windows version you are using and it is a very visual task.
Googling "How to schedule a task in Windows" will return way better / more specific / updated results than the one I could clumsily explain here.
Here's a nice one I have found for you.

Read the amazing answer by Meki here on StackOverflow.
Having a script that does a thing at discrete intervals taking control of its own destiny like that makes me squirrely. I would use an external scheduling framework to run this job at discrete intervals. In Linux, this can be done with cronjobs; in Windows, it can be done with Task Scheduler.
Linux:
In terminal, type
crontab -e
to edit the cron schedule for the current user context. Docs on editing cron can be found all over the internet - here's one: https://www.raspberrypi.org/documentation/linux/usage/cron.md
Windows:
You can schedule a python script to run on that schedule in Windows Task Scheduler. here's a link walking through that: https://www.esri.com/arcgis-blog/products/product/analytics/scheduling-a-python-script-or-model-to-run-at-a-prescribed-time/
be certain to utilize the "if the task is already running" and "run task as soon as possible after a scheduled start is missed" options if you do this method to control appropriate behavior:
I have a Python program I run at all times of the day that alerts me when something I am looking for online is posted. I want to give this to my employees but I only want to have it email them during business hours.
I have a Ubuntu server and use a .sh. I have a command in crontab that runs on startup.
How do I make my command run from 9-5?
You could create a cronjob that starts the script every 5 minutes (or whatever often you want it to run) and additionally modify the script such that it creates a .lock file which it removes on exiting, but if it encounters it at the beginning it won't do anything (this way you don't have a long-running script active multiple times).
I am working on web crawler app to download the stock price every ten minutes. I am able to extract the quote but I am not sure how to schedule it to run every ten minutes for the entire day.
Please suggest me either time loop kind of a thing or the solution for the web crawler app itself.
I need a solution which works on Windows.
Ok, so you have a python function f() which you want to execute every ten mins for a day. You can do this:
import time
while True: #Infinite loop
f() #Execute the function
time.sleep(600) #Wait 600s (10 min) before re-entering the cycle
And you keep the script running for as long as you need (a day, a week, whatever, it will not close by itself)
you can do try this
import time
and but this code before dawnload method
time.sleep(10*60) #this will stop the program for 10 minutes
Use crontab. Open the crontab file via terminal:
$ crontab -e
At the end of the file you can set the python script and the frequency of running it. For example to run a script every 10 mins:
*/10 * * * * /path/to/script
Windows has a Task Scheduler built-in. You can use that to run your script:

Schedule Python Script - Windows 7
Otherwise, you can write an infinite loop that will check the stock prices every ten minutes using something like time.sleep(600). Note that you can add your program to run at startup fairly easily:

how to start a python file while window starts?
I'd like to know how to preform an action every hour in python. My Raspberry Pi should send me information about the temp and so on every hour. Is this possible?
I am new to python and linux, so a detailed explanation would be nice.
write a python code for having those readings from sensors in to text or csv files and send them to you or to dropbox account
and then put a cron job in linux to run that python script every hour
type in your command line
sudo su
then type
crontab -e
In opened file enter:
/ 0 * * * * /home/pi/yourscript.py
where /home/pi/yourscript.py is your fullpath to python script and it will execute this "yourscript.py" every 60 min.
To send your code to you - you have to choose some way-
1) you can send it to your inbox
2) to dropbox account
3) to sql data base
In any case you have to write script for that.
you can check out the sched module (in the Python standard library).
personally, I'd keep it simpler, and just run your script every hour using a system scheduler like cron.
a basic crontab entry to run hourly (on the hour) might look like this:
0 * * * * /home/foo/myscript.py > /dev/null 2>&1
if you really want to write a scheduler in Python, see some of the answers given here: How do I get a Cron like scheduler in Python?
The easiest way would be to set up a cron job to call a python script every hour.
