If you want to call a function after typing in the entry field, you will have to use event handler and bind the entry field to event like press of return and some function xyz. which means after pressing return, a function xyz can be called.

To update a message according to entry, you will need a variable string as argument to entry.

define a text variable globally:

m=StringVar()

in Eample class add:

you could add variable text to entry field

inputfield = Entry ( self,textvariable=m )

self.inputfield.bind('<Return>',self.xyz)  #to call xyz which you may want to define

and add textvariable to message to update it

message = Message(self,textvariable=m) #to update continuously the message which i hope you meant by "live"
