I'm specifically asking about binding a keyboard keystroke to a button in a GUI. Originally I planned to bind the keystroke to the GUI button itself, but that seemed impossible, and potentially unwise after I considered it later.`

Is this the proper(, pythonic) way to bind a keyboard key and GUI button? 

    ## start.py
    print 'start'
    
    #from tkinter import *
    from Tkinter import *
    import os
    from PIL import ImageTk, Image
    
    class MyClass:
        '''This is my class.'''
    
        imgpath = '/Users/user/Dropbox/Camera Uploads'
        imgfile = 'susshi.jpg'
        #imgfilepath = os.path.join(self.imgpath, self.imgfile)
        imgfilepath = os.path.join(imgpath, imgfile)
    
        def __init__(self,master):
            print 'in __init__'
    
            # Create and load a frame into the tk (tkinter) window.
            frame = Frame(master)
            frame.pack()
    
            # Create and load two buttons in to the above-created frame.
            self.button = Button(frame, text="QUIT", fg="red", command=quit)
            self.button.pack(side=LEFT)
            self.slogan = Button(frame, text="Hello", command = self.f)
            self.slogan.pack(side=RIGHT)
            
            # Bind a key to each button from above.
            master.bind('q', quit)
            master.bind('f', self.f)
            
            # Open the image, resize it...
            self.image = Image.open(self.imgfilepath)
            self.image.thumbnail((600,600))
            # Make a tkinter-friendly image object ...
            self.display_image = ImageTk.PhotoImage(self.image)
            # Make a tkinter canvas, plug in the image, and pack the canvas.
            self.canvas = Canvas(master, bg='red')
            self.canvas.create_image(0,0, image=self.display_image, anchor="nw")
            self.canvas.pack(fill=BOTH, expand=1)
            ### FIXME: Set canvas focus!
            
        def f(self, event=None):
            print 'in f()'
            return 'hello world'
            
        def get_image_list(self):
            pass
        
        def next_image(self):
            pass
        
        def previous_image(self):
            pass
    
        def load_image(self):
            #stub
            pass
            
        def update_image(self):
            pass
        
    root = Tk()
    abc = MyClass(root)
    root.mainloop()
    
    print 'abc has been defined'
    print '"abc.f()" returns "%s"' % abc.f()
    #print str(abc.f)
    #print repr(abc.f)
    
    print 'end'

The intention of the project is to make a simple image viewer in python, with buttons in the GUI for basic navigation functions, and keys mapped to those same functions.
