Frame是一个类,用于生成自身的一个实例,可是在下面的代码片段中(来自python编程金典)高亮的一行里,
Frame的参数是自身的一个实例,这该如何理解呢?

class CheckFont( Frame ):
   """An area of text with Checkbutton controlled font"""

   def __init__( self ):
      """Create an Entry and two Checkbuttons"""
      Frame.__init__( self )
      self.pack( expand = YES, fill = BOTH )
      self.master.title( "Checkbutton Demo" )

      self.frame1 = Frame( self )
      self.frame1.pack()
