How to connect the line button with line function. The line function should work whenever the button is pressed.

What I have tried:

from tkinter import *
root =Tk()

# Width x Height
root.geometry("1366x768")
canvas_width = 1200
canvas_height = 500
w = canvas_width // 2
h = canvas_height // 2
my_canvas = Canvas(root, width=canvas_width, height=canvas_height, bg='light gray', scrollregion=(0, 0, 800, 1000))


# Create the button
b1 = Button(root, text="Line", bg="Red")
b1.pack()

# Cretae the line function
coords = {"x": 0, "y": 0, "x2": 0, "y2": 0}
final = []
lines = []


def click(e):
coords["x"] = e.x
coords["y"] = e.y
lines.append(my_canvas.create_line(coords["x"], coords["y"], coords["x"], coords["y"], fill='red', width=1))


def release(l):
lis = []
lis.append(coords["x"]);
lis.append(coords["y"]);
lis.append(coords["x2"]);
lis.append(coords["x2"])
final.append(lis)


def drag(e):
coords["x2"] = e.x
coords["y2"] = e.y
my_canvas.coords(lines[-1], coords["x"], coords["y"], coords["x2"], coords["y2"])

my_canvas.bind("<buttonpress-1>", click)
my_canvas.bind("<b1-motion>", drag)
my_canvas.bind('<buttonrelease-1>', release)
my_canvas.pack()



mainloop()
