How to get X,Y coordinate with mouse click with enabling snapping so that only line's vertex point coordinates will be selected.

By using following code i can get latitude longitude of clicked position in map canvas of QGIS but cannot enable the snapping option .

from qgis.gui import QgsMapToolEmitPoint
class PrintClickedPoint(QgsMapToolEmitPoint):
    def __init__(self, canvas):
        self.canvas = canvas
        QgsMapToolEmitPoint.__init__(self, self.canvas)

    def canvasPressEvent( self, e ):
        point = self.toMapCoordinates(self.canvas.mouseLastXY())
        point = list(point)
        iface.mapCanvas().snappingUtils().toggleEnabled()
        print(point)

canvas_clicked = PrintClickedPoint( iface.mapCanvas() )
iface.mapCanvas().setMapTool( canvas_clicked )
