[python]使用psutil模块判断程序是否在进程中

import psutil
def ifProcessRunning(process_name='WeChat.exe'):
    # 判断某个程序是否在运行
    # 原理：获取正在运行程序的pid，通过pid获取程序名，再按程序名进行判断
    pl = psutil.pids()
    result = "PROCESS_IS_NOT_RUNNING"
    for pid in pl:
        if (psutil.Process(pid).name() == process_name):
            if isinstance(pid, int):
                result = "PROCESS_IS_RUNNING"
    return result

也可以使用下面方式

import psutil
 
def is_process_running(process_name):
    for proc in psutil.process_iter(['name']):
        try:
            if process_name.lower() in proc.info['name'].lower():
                return True
        except (psutil.NoSuchProcess, psutil.AccessDenied, psutil.ZombieProcess):
            pass
    return False
 
# 使用示例
if is_process_running('你的进程名'):
    print('进程正在运行')
else:
    print('进程未运行')
