title: python: multiple variables using tuple
body: <p>I was reading about <code>tuple</code>:</p>
  
  <blockquote>
    <p>Once created, the values of a tuple cannot change.</p>
    
    <p>If you want to assign multiple variables at once, you can use tuples:</p>
  
  <pre><code>name,age,country,career = ('Diana',32,'Canada','CompSci')
  print(country)
  </code></pre>
  </blockquote>
  
  <p>I did this..</p>
  
  <pre><code>country = 'India'
  print(country)
  </code></pre>
  
  <p>and it's modified. How come?</p>
