title: Python: Inserting text after a tab in a text file
body: <p>I want to insert some text after a tab character in a textfile. How can I do this in python? </p>
  
  <p>I have tried using Python seek() function. But is does not seem to take <code>'\t'</code>(for tab) as an argument.</p>
  
  <p>Thanks.</p>
