Help with GUI

[BlazingD4NG3R]

Hey so I am learning python and i am doing stuff with tkinter and GUIs. I am trying to make a quiz however there is an error and i dont quite know how to fix it. the error is on line 21 and here is what it says

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Users\Invate\AppData\Local\Programs\Python\Python36-32\lib\tkinter\__init__.py", line 1699, in __call__
    return self.func(*args)
  File "C:/Users/Invate/Desktop/Stuff/quiz.py", line 21, in click2
    output.delete(0.0, END)
  File "C:\Users\Invate\AppData\Local\Programs\Python\Python36-32\lib\tkinter\__init__.py", line 2673, in delete
    self.tk.call(self._w, 'delete', first, last)
_tkinter.TclError: bad entry index "0.0"

it happens when i run and press the get answers button i made.

from tkinter import *
import random

window = Tk()
window.title("Quiz")

question = ""

def click():
    questions = list(questionslist.keys())
    question = random.choice(questions)
    question1.insert(END, question)

def click1():
    questions = list(questionslist.keys())
    question = random.choice(questions)
    question1.delete(0.0, END)
    question1.insert(END, question)

def click2():
    output.delete(0.0, END)
    try:
        answers = questionslist[question]
    except:
        answers = "There is no entry for this word."
    output.insert(END, answers)


b = "Get Question"
getquestion1 = Button(window, text=b, width=10, command=click1).grid(row=0, column=0, sticky=W)

b2 = "Get Answer"
getquestion1 = Button(window, text=b2, width=10, command=click2).grid(row=3, column=0, sticky=W)

question1 = Text(window, width=40, height=3, wrap=WORD, background="light green")
question1.grid(row=2, column=0, columnspan=2, sticky=W)

output = Entry(window, width=75, bg="light green")
output.grid(row=4, column= 0, sticky=W)

questionslist = {
    'What is 1+1?': "2"
}
window.mainloop()

0.0 is apparently not a valid index. Try just 0, since floats don't make sense as indexes anyway.

This code is messed up.
Start small, you try to do too much too fast.
If you work small portions of the code at a time, you will not have a problem in the end
Obvious problems:
getquestion1 button declared twice you will never see the first one
nothing is in a class, but you are referencing (for example question1) before it is declared.

Suggestion start over. get one thing working and then start with the second.
