i have a GUI that outputs a text among other things. after input form
user i want this text to be *)cleared and/or

Which widget do you use?

Some widgets can be connected to variables so that when the variable
changes the widget is automatically update.
Have a look <at http://docs.python.org/lib/node696.html>.

i know how to do this already. the problem is i want the text to stay
in the windowa nd not start overwriting "Answer:".
i have solved this by using an Entry for the answer as well but id
prefer using a Label.

You can set the width option of the Label. For example:

b = Label(mygui, text=eval(expr) , width=20)

Then the Label will always be 20 characters wide no matter how long
the answer is.
You can read more about the options for Tk widgets in <http://
www.tcl.tk/man/tcl8.5/TkCmd/contents.htm>.

Then don't use `place()` but let Tkinter handle the layout with the pack
and/or grid layout manager. GUIs with `place()` are a bad idea because
the GUI may look odd or is even unusable on other peoples computers with
other screen resolutions, fonts, and font sizes.
