title: Setting focus to specific TKinter entry widget
body: <p>I'd like to set the focus of my program to a specific <code>entry</code> widget so that I can start entering data straight-away - how can I do this?</p>
  
  <p><strong>My current code</strong></p>
  
  <pre><code>from Tkinter import *
  root = Tk()
  frame=Frame(root,width=100,heigh=100,bd=11)
  frame.pack()
  label = Label(frame,text="Enter a digit that you guessed:").pack()
  entry= Entry(frame,bd=4)
  entry.pack()
  
  button1=Button(root,width=4,height=1,text='ok')
  button1.pack()
  
  root.mainloop()
  </code></pre>
