find any item in the list

[snippsat]

great its working but now how i cant now which of pro_find = ["opera.exe" , "chrome.exe" , "iexplore.exe" , "firefox.exe" , "microsoftedgecp.exe"]
exist

Can compare lists,set() is best as there can be several process with same name.

>>> process_list[:6]
['Registry',
 'smss.exe',
 'csrss.exe',
 'wininit.exe',
 'csrss.exe',
 'winlogon.exe']
>>> pro_find =  ['csrss.exe', 'smss.exe', "firefox.exe"]
>>> p = set(pro_find) & set(process_list)
>>> p
{'csrss.exe', 'smss.exe'}

So firefox.exe is not running.

exist and pass it name to

I don't understand what you try to do here,it just process names a dir will not work without a absolute path.
Should you be using os.popen()
