Python item-input on windows-system

Number Temp01 "Temperature [%.1f °C]" {exec="<[/usr/bin/python /home/pi/temp.py:10000:REGEX((.*?))]"}

How is the path to change for running on a windows-system. I tried different entrys, but get no value and no entry in the log-files.
Python works and the EXEC-Bindung is installed.
I can’t find a working example.
Can anyone help please?
