Introduction to the "Schedule" in Python
Introduction to the "Schedule" in Python
Overview:
'Schedule' is a flexible and easy -to -use library based on Python, which is used to perform duplicate tasks at a specified time.It provides a simple way to create and manage timing tasks, whether one -time or repeated tasks.By using the 'Schedule' library, developers can write code in order to perform tasks in a specific time interval or at a specific date and time.
Install:
To install the 'SCHEDULE' library, you can use the PIP (Python package management tool) to run the following commands in the command line:
pip install schedule
The main function:
1. Create task: Use the 'SCHEDULE' library to create a task by defining a function. This function will be executed at a specific date and time.
2. Set time interval: The library allows developers to define the time interval between tasks and repeat the task according to the set time interval.
3. Specify Date and time: Use the 'SCHEDULE' library to perform tasks execute at a specific date and time instead of repeatedly executed according to a fixed time interval.
4. Asynchronous task: The library also supports asynchronous tasks and can perform other operations during task execution.
Code example:
Below is a simple example of using the 'Schedule' library. This example creates a timing task to print Hello World information:
python
import schedule
import time
def job():
print("Hello World")
schedule.every (5) .seconds.do (job) # performed every 5 seconds to perform tasks
while True:
schedule.run_pending()
time.sleep(1)
Explanation and configuration:
1. First, introduce the time module of 'Schedule' library and python.
2. Define a function `job ()`, this function will print "Hello World" information when calling.
3. Use `schedue.every (5) .seconds.do (job)` statement, set a repeated task, this task executes a function `job ()` every 5 seconds.
4. Then, use an unlimited cycle to call the `schedule.run_pending () function, which will check whether there is a task to run and perform the corresponding tasks.
5. Use `Time.sleep (1)` to avoid the cycle too frequently and the interval for 1 second.
By simply modifying the time interval and task functions in the code, you can create and manage regular tasks according to your own needs.
Summarize:
'Schedule' is a powerful and convenient tool for managing timing tasks in Python.It has flexible functions, can easily create various types of timing tasks and adjust according to needs.Whether as a personal project or a commercial application, using the 'Schedule' library can easily process time management and task scheduling.
