The method of using Pstuil class libraries to implement inter -process communication is used to implement inter -process communication
In Python, you can use the PStuil class library to achieve inter -process communication (IPC).PSTUIL is a powerful library that can be used to manage and control the process.
Inter -process communication refers to interaction and coordination between processes through data exchange.In some cases, multiple processes need to share data or notify their state changes.At this time, the communication mechanism used by the process is very useful.
In Python, you can use the Communication module of the PStuil library to achieve inter -process communication.The following is an example code:
python
import psutil
from psutil._common import bytes2human
def get_running_processes():
# Get the process of all current operations
processes = psutil.process_iter(['pid', 'name', 'status', 'memory_info'])
for process in processes:
try:
pid = process.info['pid']
name = process.info['name']
status = process.info['status']
memory_info = bytes2human(process.info['memory_info'].rss)
Print (f "process ID: {pid} \ t Substitution name: {name} \ t Standard: {Status} \ t Memory Occupation: {Memory_info}")
except (psutil.NoSuchProcess, psutil.AccessDenied, psutil.ZombieProcess):
pass
if __name__ == '__main__':
get_running_processes()
In the above example code, we first introduced psutil and psutil._common.bytes2human.PSUTIL is a cross -tier library for process and system monitoring, and PSUTIL._COMMON.BYTES2HUMAN is used to convert byte size to human readable formats.
We then define a function called get_running_processses.This function uses the PSUTIL.Process_iter method to obtain the current processes in all operations, and then obtain its relevant information by iterating each process.We have printed the process ID (PID), process name, status and memory occupation of each process.
Finally, call the get_running_processses function in the main function.
This example code demonstrates how to use the PStuil class library to obtain the process and its related information in operation.You can further expand the code according to your needs to achieve specific inter -processing functions.
The method of using the PStuil class library to implement inter -process communication includes:
1. Get the process list: You can use the PSUTIL.Process_iter method to obtain all the processes in the operation, and access the information of each process, such as process ID, process name, status, etc.
2. Process information exchange: The process can perform information exchange through sharing memory, pipelines, signals, etc.For example, using queue, shared memory, socket and other mechanisms, processes can share variables, send messages, etc.
3. Process synchronization and mutual exclusion: use the lock mechanism to ensure the synchronization and mutual exclusion of sharing data between processes.Common lock mechanisms include mutual locks, semaphores, condition variables, etc.
It should be noted that the specific methods and implementation of inter -process communication will be different according to specific needs and scenes.The PStuil class library provides some basic interfaces and tools for us to easily manage and control the process.By using these interfaces and tools flexibly, we can implement the functions of communication between various processes.
