Ok. The correct code should be:
for i in range(1,nbs+1) :
pAis=AIS_Shape( step_reader.Shape( i )).GetHandle()
display.Context.SetColor(pAis,Quantity.Quantity_NOC_DARKVIOLET,0)
display.Context.Display(pAis, True )
or, better:
for i in range(1,nbs+1) :
display.DisplayColoredShape( step_reader.Shape( i
),Quantity.Quantity_NOC_DARKVIOLET)
