That can be changed for app after creating root window and IDLE does so. 
  See idlelib/pyshell.py (in 3.6, PyShell.py previously), after "# set 
application icon".  Code is different for Windows and *nix/Mac.

This is set during installation.  I *presume* (but know no details) that 
icon file is loaded somewhat and appropriate registry setting connects 
app to icon file.
