If that is a direct Python string, then you're not changing the string. Python 
strings are immutable. So, then you're at most changing which string a variable 
or attribute is referring to.

However, if it is some Tkinter thing (I seem to recall that Tkinter offers some 
automatic update magic via something-something), then I don't know.

Just update the widget whenever you change the text.
