Bug report
Double nested arrays in tk.coords will produce errors in tkinter (_tkinter.TclError: wrong # coordinates: expected at least 4, got 2 in this case)
import tkinter as tk
coords = [[100, 100], [300, 300]]
root = tk.Tk()
canvas = tk.Canvas(width=400,
height=400,
background="bisque")
canvas.pack(fill="both", expand=True)
line = canvas.create_line(coords)
coords[1] = [200, 200]
canvas.coords(line, coords) # line with error
root.mainloop()
