You could write your function so that it takes any number of arguments:

deffunction(*args):
    #args is now a tuple containing every argument sent to this functionprint("Here are some words.")

Alternatively, you could keep your function as it is, and use a lambda to discard the unused self value:

input_widget.bind("<Return>", lambda x: function())

Add this to your binding:

input_widget.bind("<Return>", lambda event: function())

Event bindings all require an event parameter which is automatically passed to the function. By using a lambda with the parameter event; you can take in this "event" variable and basically discard it and do whatever is in function()
