Tkinter Canvas

Hello I am trying to make a simple program that will move the turtle specified by the keyboard input and I would like to have a list of controls on the right. This is my code so far

Code:

from turtle import *
import tkinter

key1 = 1

Controls = tkinter.Tk()
Controls.title("Color")
Controls.minsize(100, 100)
cv = tkinter.Canvas(Controls, bg = "gray")
cv.pack(side = tkinter.LEFT)
t = RawTurtle(cv)
t.pensize(3)

w = tkinter.Label(Controls, text="Arrow Keys - Move")
w.pack()

def k1():
    global key1
    key1 +=1
    while key1 % 2 == 0:
        t.pencolor(random.choice(colors))
        t.forward(5)

onkey(k1, "Up")

listen()
mainloop()

I don't think I am implementing the Canvas correctly.

Your code modified to print which key was pressed, Up, Down, etc. And a tutorial on the Canvas module

Code:

def to_key(event):
    print event.keysym

key1 = 1

Controls = tkinter.Tk()
Controls.title("Color")
Controls.minsize(100, 100)
Controls.bind("<KeyPress>", to_key)
#cv = tkinter.Canvas(Controls, bg = "gray")
#cv.pack(side = tkinter.LEFT)
#t = RawTurtle(cv)
#t.pensize(3)

w = tkinter.Label(Controls, text="Arrow Keys - Move")
w.pack()

def k1():
    global key1
    key1 +=1
    while key1 % 2 == 0:
        t.pencolor(random.choice(colors))
        t.forward(5)

#onkey(k1, "Up")

#listen()
Controls.mainloop()
