Here is a quick overview of how to use the wm (window manager) call function:

#!/usr/bin/python3

from Tkinter import *
frame = Tk()

frame.overrideredirect(1) # Remove shadow & drag bar. Note: Must be used before wm calls otherwise these will be removed.

frame.call("wm", "attributes", ".", "-topmost", "true") # Always keep window on top of others
frame.geometry("100x100+500+500") # Set offset from top-left corner of screen as well as size
frame.call("wm", "attributes", ".", "-transparent", "true") # Remove shadow from window
frame.call("wm", "attributes", ".", "-fullscreen", "true") # Fullscreen mode
frame.call("wm", "attributes", ".", "-alpha", "0.9") # Window Opacity 0.0-1.0
frame.call("wm", "attributes", ".", "-modified", "0.9") # Toggles modified state of the close-window icon.

frame.mainloop()

The "." is the 'path' to the window name in case it is a child of another window. For example if window "myFrame" had a child called "popup" then the path would read as "myFrame.popup". The values true and false can be replaced with 1 and 0 respectively. Note: 1 and 0 do not need quotation marks.
