title: Why sys.stdout.write() display the length of the string?
body: <pre><code>&gt;&gt;&gt; import sys
  &gt;&gt;&gt; sys.stdout.write("Hello")
  Hello5
  &gt;&gt;&gt; sys.stdout.write("My name is something")
  My name is something20
  &gt;&gt;&gt;  
  </code></pre>
  
  <p>As you see on the codes above, the outputs with the length of the string. Wondering why? Why this method display the length? Is there something special that I missed?</p>
