[Tkinter] Get the last entry in my text widget

[Pedroski55]

Thank you very much! I strained my brain making this work! Getting the penultimate line was tricky.

Obviously, your code is much better than mine! I don't know about float.

Just out of interest, this is what I did (the extra output is so I can see what is happening, I'll block that later):

def retrieve_input():        
        pos = text_area.index("end-1c")
        lineNum = pos.split('.')        
        line = int(lineNum[0]) - 1
        #echoMessage(str(line))
        pos2 = str(line) + '.0'
        answer = text_area.get(pos2, 'end-1c')        
        echoMessage('answer is ' + answer)
        echoMessage('pos is ' + pos)
        echoMessage('pos2 is ' + pos2)
        echoMessage('line number echoed was ' + str(line))
        return pos2;

Still using the window you made, I added a button 'Submit answer'

My little 'makehtmltable.py' asks me if I want to continue. It needs a 'y' to carry on. Now I can give it a y. This is the output in the text widget

Enter y to continue, enter nothing to stop.
y
answer is y

Thanks again for your help!
