Example tutorials of PStuil class library and Python process management
PSTUIL is a powerful Python library that is used to manage process -related tasks in the operating system.It provides many methods that can easily manage the creation, searching, and termination of the process.This article will introduce how to use PSTUIL to manage processes and demonstrate some common cases.
Before starting the tutorial, you need to ensure that the PStuil library has been installed correctly.
Step 1: Import the necessary library
First, let's import the required libraries.In addition to PSTUIL, we will also use other common Python libraries, such as time libraries and random generating glory:
python
import psutil
import time
import random
Step 2: Create the process
python
def create_process():
pid = psutil.Process().pid
print(f"New process created with PID: {pid}")
time.sleep(random.randint(1, 5))
Step 3: Find the process
Using PSTUIL's Process_iter () method, we can obtain information about all processes currently running in the system.The following code will find and display the ID and name of all processes in the system:
python
def find_processes():
for process in psutil.process_iter():
process_id = process.pid
process_name = process.name()
print(f"Process ID: {process_id}, Process Name: {process_name}")
Step 4: Termination process
If we need to terminate a process, we can use the Terminate () method of pstting.The following code will select a process in the system and terminate the process:
python
def terminate_process():
processes = list(psutil.process_iter())
if len(processes) > 0:
process = random.choice(processes)
process_name = process.name()
process.terminate()
print(f"Terminated process with name: {process_name}")
else:
print("No processes found to terminate.")
Step 5: Run example
Now, we can write a simple script to run these methods.The following code will run each of the above methods in order and perform some simple demonstrations:
python
if __name__ == '__main__':
create_process()
print("----------")
time.sleep(2)
find_processes()
print("----------")
time.sleep(2)
terminate_process()
This script first creates a new process, and then wait for 2 seconds to find and display the information of all processes, wait for another 2 seconds, and finally stop a process randomly.
Note: In the above code example, we just show the basic usage of the PStuil library.In practical applications, you may need to modify and optimize the code according to specific needs.
Summarize:
This tutorial introduces how to use PStuil library to manage the process in Python.We have learned how to create processes, finds processes, and terminate processes, and provide relevant example code.With PStuil, you can easily perform process management tasks to meet your needs.I hope this tutorial will help you!
