Python Scheduler

A scheduler

is used to run the function periodically using different types of patterns and syntaxes. Normally, if a task has to be performed every time after a specific time difference, a scheduler can be used.

Suppose you have a report which needs to be generated at 10 AM daily, this process can be triggered using a scheduled program.

Python has a β€œschedule” library that can help you perform this scheduling using very friendly syntaxes.

Official documentation of this library is available at https://schedule.readthedocs.io/en/stable/

To use this library you will need to install it using



pip install schedule

Now you are ready to schedule the jobs.

Let's try a simple example



import schedule
import time

# This method is the actual processing that we want to accomplish
# with every scheduled execution
def job():
    print("Job ran")

# This defines the frequency to run the program
schedule.every().hour.do(job)

# while loop to keep the program running in the memory
while True:
        # it will check if any execution is pending, 
        # if yes it will start execution
    schedule.run_pending()

        # program will sleep for 1 second and then will again start while loop
    time.sleep(1)


Enter fullscreen mode Exit fullscreen mode

The above program will run every hour and print the line β€œJob ran”.

Let's look at some more examples to schedule job syntaxes

Scheudled job with frequency



# Run job every 15 seconds
schedule.every(15).seconds.do(job)

# Run job every 15 minutes
schedule.every(32).minutes.do(job)

# Run job every 12 hours
schedule.every(12).hours.do(job)

# Run job every 5 days
schedule.every(5).days.do(job)

# Run job every 2 weeks
schedule.every(2).weeks.do(job)


Enter fullscreen mode Exit fullscreen mode

Scheduled job for specific time



# Run job every minute at the 45th second
schedule.every().minute.at(":45").do(job)

# Run job every hour at the 10th minute
schedule.every().hour.at(":10").do(job)

# Run job every day at specific time

# Everyday at 11 Hour 11 Minutes
schedule.every().day.at("11:11").do(job)

# Everyday at 11 Hour 11 Minutes 11 Second
schedule.every().day.at("11:11:11").do(job)
