it giving error typeerror: init() takes 2 arguments (3 given). please me

you can add variable init function , set none when no value passed

# frame form class simpleform_ap(tk):     def __init__(self,parent, entered_value=none):         tk.__init__(self,parent)         ..         .. 

also want pass method or class parent in line

self.app = simpleform_ap(self.selection, enterednumber)   # send demo3 argument 

you may want pass self instead of self.selection
