python判断进程是否存在

代码：

def check_exsit(process_name): 
import win32com.client 
WMI = win32com.client.GetObject('winmgmts:') 
processCodeCov = WMI.ExecQuery('select * from Win32_Process where Name="%s"' % process_name) 
if len(processCodeCov) > 0: 
print '%s is exists' % process_name 
else: 
print '%s is not exists' % process_name 

if __name__ == '__main__': 
check_exsit('chrome.exe')
