win32com.client.Dispatch() is the equivalent:

import win32com.client
ob = win32com.client.Dispatch("WbemScripting.SWbemRefresher")

However, a quick google should have told you that (searching for 'python
wmi' on google shows lots of relevant hits)

Many of the relevant functions have a 'machine' param which is the name of
the machine the function should operate on - again 'python pdh' at google
lists relevant results.
