title: Tkinter Canvas is not showing
body: <p>So I was trying to make a countdown in python using tkinter, but somehow the canvas windows is not showing... I don't really know why, can anyone help me?</p>
  
  <pre><code>import tkinter
  import random
  import time
  canvas=tkinter.Canvas(height=350,width=400,)
  canvas.pack()
  
  t=10
  
  def c():
      global t
      while t&gt;=0:
          if t == 0:
              canvas.create_text(100,10, text="YOU LOST!")
  
  
          else:
              time.sleep(1)        
              t-=1
              canvas.create_text(50,50, text=t, font="Aria 25", fill="red")
              print(t)            
  
  c()
  </code></pre>
