Launch python script in .desktop without root privileges

I've made a script on My Raspberry Pi (Rasbian Jessie) where I made a .desktop file to launch a Python script from the desktop.

When I open nautilus and go to the desktop path, the file runs. But when I double-click it from the desktop (without root privileges) nothing happens.
