Destroy Tkinter Button After Click

I have a Tkinter list box populated with city names. I want to grab the selected value and pass it to subsequent code after the mainloop. I have the following tkinker code: master

Solution 1:

Your button doesn't destroy because its function 'returns' before doing so. Which is also bad because a command's callback method can't really return anywhere meaningful. Do the following changes:

some_outer_scope_var = None

def ok():
    global some_outer_scope_var
    some_outer_scope_var = variable.get()
    print ("value is:" + variable.get())
    master.destroy()

That way you save the value of variable.get() on some_outer_scope_var first and then destroy all GUI.

Solution 2:

Try using button.destroy() if you want to destroy the button only.
