Cross-platform way to get PIDs by process name in python

Question

Several processes with the same name are running on host. What is the cross-platform way to get PIDs of those processes by name using python or jyth

Answer 1

There's no single cross-platform API, you'll have to check for OS. For posix based use /proc. For Windows use following code to get list of all pids with coresponding process names

from win32com.client import GetObject
WMI = GetObject('winmgmts:')
processes = WMI.InstancesOf('Win32_Process')
process_list = [(p.Properties_("ProcessID").Value, p.Properties_("Name").Value) for p in processes]

You can then easily filter out processes you need. For more info on available properties of Win32_Process check out Win32_Process Class
