Whilst not specifically neat, you can use global variables to store the start position for usage later.

Consider the below example

from tkinter import *

root = Tk()

start_pos = None

def start_mouse_press(event):
    global start_pos
    start_pos = (event.x, event.y)

def stop_mouse_press(event):
    print(f"Start Pos {start_pos}\nEnd Pos {event.x, event.y}")


root.bind("<ButtonPress-1>", start_mouse_press)
root.bind("<ButtonRelease-1>", stop_mouse_press)

The start position is recorded so that when the mouse button is released, both the start and end positions can be printed.

You will never be able to access event outside of the function of which event is an argument.

This is a matter of scope, if you wish to use event elsewhere, pass event as an argument to the next function you wish to use it in.
