如何使用python从windows的任务管理器中获取特定进程的cpu使用率？

pip install psutil

import psutil

def get_cpu_usage(process_name):
    for proc in psutil.process_iter(['pid', 'name', 'cpu_percent']):
        if proc.info['name'] == process_name:
            return proc.info['cpu_percent']
    return None

process_name = 'your_process_name'  # 替换为你要获取CPU使用率的进程名
cpu_usage = get_cpu_usage(process_name)
if cpu_usage is not None:
    print(f"CPU usage of {process_name}: {cpu_usage}%")
else:
    print(f"Process {process_name} not found")
