title: Click button to pop up new window with random color on python 3
body: <p>We were planning to play colored Jenga with my kids and realized that we lost a dice with three colors (yellow, blue, red). I decided to write a program to generate random three colors. My program does not open a new window. </p>
  
  <pre><code>from tkinter import *
  import random
  def get_color():
    a = ['blue', 'red', 'yellow']
    print(random.choice(a))
  Button(text='Select Color', command=get_color).pack()
  mainloop()
  </code></pre>
