I am working on the file "Python/Chapter-06/2-3-Trees-Frame.ipynb".
The first task is:
The class Method is not used in the implementation of 2-3 trees. It is only used for displaying method calls in equations. It is displayed as a rectangle containing the string that is stored in the member variable mLabel.
Can you write Python program for it?
 ... Give me a the Python program you requested?

#Here is the Python program you requested.

class Method(TwoThreeTree):
    def __init__(self, label):
        TwoThreeTree.__init__(self)
        self.mLabel = label
        
    def __str__(self):
        return self.mLabel
    
    def isMethod(self):
        return True
