title: Change coords of line in python tkinter canvas
body: <p>I've drawn a line in <code>tkinter.Canvas</code> and now I want to move one end. Is this possible, e.g. with <code>itemconfig</code>?</p>
  
  <pre><code>import tkinter
  
  tk = tkinter.Tk()
  canvas = tkinter.Canvas(tk)
  canvas.pack()
  line = canvas.create_line(0, 0, 100, 100)
  tk.mainloop()
  </code></pre>
  
  <p>Now I want to change the end of the line to <code>75, 25</code>. Is there a better way as to delete the line and create a new one? </p>
