+This example shows you how you can capture mouse click events in tkinter
+'''
+#import the library
 from tkinter import *
-
+#create a window object
 root = Tk()
-
+#create the function to handle the click events
+#note that event is a special object in tkinter that will be generated each time there is a click
 def callback(event):
+    #note that we can do other things with our x and y now that we know how to get them
     print ("clicked at", event.x, event.y)
 
+#setup the window size
 frame = Frame(root, width=400, height=400)
+#everything in the window will be considered a button, which calls the callback function when pressed
 frame.bind("<Button-1>", callback)
+#put the sizing and button definition into our window (pack is the simplest method)
 frame.pack()
 
+#title the overall window
+root.title("Example of capturing a mouse click location.")
+#show the window - windows run in a loop listening for the window close button to break the loop
 root.mainloop()
