Changing values based off variables in Python
I'm trying to make a text go from '0' when a box hasn't been clicked to '1' when it has been clicked. However, the variable I have sets the text as '0' before it is clicked, and so when the box is clicked and the variable is changed, the text isn't changed. Here's the code.
from tkinter import *
root = Tk()
height = 500
width = 500
canvas = Canvas(width=width, height=height)
root.title = "Test"
def click(event):
item = canvas.find_closest(event.x, event.y)
tags = canvas.gettags(item)
if tags[0] == 'rect1':
canvas.itemconfig(item, fill="blue")
click.value = '1'
click.value = '0'
text = click.value
canvas.create_rectangle(100, 100, 400, 400, tags='rect1', fill='white')
canvas.create_text(200, 300, font='Times 50', text=text, anchor=E)
canvas.pack()
canvas.bind("<Button-1>", click)
canvas.mainloop()
python function variables tkinter

You can't just set a variable and expect the canvas to change. You need to call itemconfigure on the text object to change the text in the exact same way that you call itemconfigure on the rectangle to change the color.
