title: Readline() in a loop is not working in python
body: <p>I have a file called <code>file</code> with this text:</p>
  
  <pre><code>Hello
  I am not a bot
  I am a human
  Do you believe me?
  I know you won't
  Yes I am a bot
  Yes you thought it right
  </code></pre>
  
  <p>This code prints out all the lines of the text:</p>
  
  <pre><code>with open(file) as f:
      for i in f:
          print(i,end="")
  </code></pre>
  
  <p>But this code does not, and I don't understand why.</p>
  
  <pre><code>with open(file) as f:
      for i in f:
          print(f.readline(),end="")
  </code></pre>
  
  <p>This prints out:</p>
  
  <pre><code>I am not a bot
  Do you believe me?
  Yes I am a bot
  </code></pre>
  
  <p>What I understand is as the loop goes over the lines in the file, it will read that line and return that as a string which is then printed.
  If I replace the for loop with <code>for i in range(9)</code>, it works.</p>
