[Tkinter] Get the last entry in my text widget

[Pedroski55]

I want to get the last entry in my text widget.

This writes an entry to the text widget (thanks to Menator01):

def printit(text):
        #text_area.delete(0.0, tk.END)
        text_area.insert(tk.END, text.get() + '\n')

I can't see how to assign this directly to a variable. But I can use:

def retrieve_input():
        #input = self.myText_Box.get("1.0",'end-1c')
        answer = text_area.get(X)

to get all the text.

What value must X have to get the last entry, the last line, in the text widget? I need to do this a few times.
