Guidance for the usage of the "Schedule 'Class Library in Python
'Schedule' is a powerful Python class library that can help developers perform tasks easily at the specified time interval.This guide will introduce the usage of the "Schedule" class library and provide some example code and related configuration.
1. Install the "Schedule" class library
Run the following commands in the terminal or command prompt to install the "schedule" class library:
python
pip install schedule
2. Import 'SCHEDULE' class library
Introduce the "Schedule" class library in the Python script to use the functions:
python
import schedule
import time
3. Basic usage
The basic usage of the "Schedule" class library is very simple. You can use the decoration or function to define the execution time of the task.Here are some commonly used methods:
-Phickule.every (interval) .seconds.do (job) `: The task is performed every second number of seconds.
-` SCHEDULE.every (). Minute.do (job) `: execute tasks every minute.
-` SCHEDule.every (). Hour.do (job) `: execute tasks every hour.
-Phickule.every (). Day.at ("10:30"). Do (job) `: Specifies every day to perform tasks.You can use a 24 -hour system to define the time.
-` SCHEDULE.every (3) .to (5) .minutes.do (job) `: execute tasks within the specified minute range.
-` SCHEDULE.every (). Monday.do (job) `: execute the task every Monday.You can also use `schedule.every (). Tuesday.do (job),` schedule.every (). Wednesday.do (job) `, etc. to specify other dates.
-` SCHEDULE.every (). Wednesday.at ("13:15"). Do (job) `: Specifies every Wednesday to perform tasks.
-` SCHEDULE.every (). Month.do (job) `: execute tasks once a month.
-` schedule.every (). Week.do (job) `: execute tasks once a week.
Please note that the above `job` refers to the function or method to be executed.
4. Execute the task
In order to perform the task as planned, we need to call the `schedule.run_pending () method in an unlimited cycle to check whether there is a task to be executed.At the same time, set appropriate delay, you can use the `Time.sleep (Seconds)` to control.
python
while True:
schedule.run_pending()
time.sleep(1)
5. Complete example code
python
import schedule
import time
def job():
print("Task executed")
schedule.every().day.at("10:30").do(job)
schedule.every().monday.do(job)
schedule.every(3).to(5).minutes.do(job)
while True:
schedule.run_pending()
time.sleep(1)
The above example code defines three tasks, executing at 10:30 daily, per Monday and every 3 to 5 minutes.You can add more tasks or modify tasks according to your needs.
This is the basic usage of the "Schedule" class library and some example code.According to your specific needs, you can flexibly adjust the execution time and interval of the task.Using the "Schedule" class library, the Python program can be easily performed according to a specific timetable.
