使用psutil库获取系统进程

首先安装库

pip install psutil -i  https://mirrors.aliyun.com/pypi/simple/

安装好页面。

下面是获取系统进程的信息：

import psutil

# 获取所有进程的详细信息
processes = psutil.process_iter()
for process in processes:
    print(process)

# 获取当前正在运行的进程
running_processes = psutil.process_iter(attrs=['name', 'pid', 'status'])
for process in running_processes:
    print(process)

# 根据进程名称获取特定进程
def get_process_by_name(process_name):
    for process in psutil.process_iter(attrs=['name', 'pid', 'status']):
        if process.info['name'] == process_name:
            return process.info
    return None

print(get_process_by_name('python.exe'))

# 根据进程ID获取特定进程
def get_process_by_pid(process_pid):
    for process in psutil.process_iter(attrs=['name', 'pid', 'status']):
        if process.info['pid'] == process_pid:
            return process.info
    return None

print(get_process_by_pid(1234))

清理同名进程

# 根据进程名称清理系统进程
def kill_process_by_name(process_name):
    for process in psutil.process_iter(['name']):
        if process.info['name'] == process_name:
            process.kill()
            print('Process'+ process_name+'has been killed.')

# 使用函数杀死名为'cmd.exe'的进程
kill_process_by_name('cmd.exe')

清理干净了
