ケース:RGBの3つのスライドバーを制御することで、領域内の色がリアルタイムで変化します.

import Tkinter as tk
window=tk.Tk()
#        
#slider=tk.Scale(window,from_=0,to=100)

#              
def sliderUpdate(source):
    red=redSlider.get()
    green=greenSlider.get()
    blue=blueSlider.get()
    colour = "#%02x%02x%02x" % (red,green , blue)
   # print colour
    canvas.config(bg=colour)

redSlider=tk.Scale(window,from_=0,to=255,command=sliderUpdate)
greenSlider=tk.Scale(window,from_=0,to=255,command=sliderUpdate)
blueSlider=tk.Scale(window,from_=0,to=255,command=sliderUpdate)
canvas=tk.Canvas(window,width=200,height=200)

redSlider.grid(row=1,column=1)
greenSlider.grid(row=1,column=2)
blueSlider.grid(row=1,column=3)
canvas.grid(row=2,column=1,columnspan=3)

tk.mainloop()

テキストボックスを追加して、このときの色の値を表示します.

import Tkinter as tk
window=tk.Tk()
#        
#slider=tk.Scale(window,from_=0,to=100)


#              
def sliderUpdate(source):
    red=redSlider.get()
    green=greenSlider.get()
    blue=blueSlider.get()
    colour = "#%02x%02x%02x" % (red,green , blue)
   # print colour
    canvas.config(bg=colour)
    #                   
    hexText.delete(0,tk.END)
    hexText.insert(0,colour)

redSlider=tk.Scale(window,from_=0,to=255,command=sliderUpdate)
greenSlider=tk.Scale(window,from_=0,to=255,command=sliderUpdate)
blueSlider=tk.Scale(window,from_=0,to=255,command=sliderUpdate)
canvas=tk.Canvas(window,width=200,height=200)

#       ，               
hexText=tk.Entry(window)

redSlider.grid(row=1,column=1)
greenSlider.grid(row=1,column=2)
blueSlider.grid(row=1,column=3)
canvas.grid(row=2,column=1,columnspan=3)

#            
hexText.grid(row=3,column=1,columnspan=3)

tk.mainloop()

ケース:一定のボタンをクリックした回数、表示時間

import Tkinter as tk
import time
window=tk.Tk()


clicks=0
start=0
goal=10

#           
def buttonclick():
    global clicks
    global start

    if clicks==0:
        start=time.time()
        clicks=clicks+1
    elif clicks+1>=goal:
        score=time.time()-start
        label.config(text="time"+str(score))
        clicks=0
    else:
        clicks=clicks+1
    slider.set(clicks)


button = tk.Button(window,text='click me',command=buttonclick)
slide=tk.Scale(window,from_=0,to=goal)
label=tk.Label(window)

button.pack()
slide.pack()
label.pack()

window.mainloop()

この行のコードに注意:

colour="#%02x%02x%02x"%(red,green,blue)  #          colour
