python检测进程是否存在

# 使用win32com来判断进程是否存在
import win32com.client
def proc_exist(process_name):
    is_exist = False
    wmi = win32com.client.GetObject('winmgmts:')
    processCodeCov = wmi.ExecQuery('select * from Win32_Process where name=\"%s\"' %(process_name))
    if len(processCodeCov) > 0:
        is_exist = True
    return is_exist

if proc_exist('chrome.exe'):
    print('chrome.exe is running')
else:
    print('no such process...')
