This is the wrong way to do it. Yes, in principle you could remove the 
label and put a new one there; but it's much better to just change the 
text of it by means of either

	labelent1.configure(text="New text ")

or by linking a variable with the label variable at the setup time
	somestringvar = StringVar("initial text")
	Label(main, textvariable=somestringvar)

and then change that variable
	somestringvar.set("New text")

Both of these don't solve the error, though; it has nothing to do with 
Tk, you just did not make labelent1 global. However, I strongly advise 
to use an object for the entire window, where you make this labelent1 an 
instance variable (put into self).
