title: Python readline with custom delimiter
body: <p>novice here. 
  I am trying to read lines from a file, however a single line in a <code>.txt</code> file has a <code>\n</code> in the middle somewhere and while trying to read that line with .readline python cuts it in the middle and outputs as two lines.</p>
  
  <ul>
  <li><p>when I copy and past the line to this window, it shows up as two lines. So i uploaded the file here: <a href="https://ufile.io/npt3n" rel="noreferrer">https://ufile.io/npt3n</a></p></li>
  <li><p>also added screenshot of the file as it shows in txt file.</p></li>
  <li>this is group chat history exported from Whatsup..if you are wondering.</li>
  <li>Please help me to read one line completely as shown in txt file.</li>
  </ul>
  
  <p>.</p>
  
  <pre><code>f= open("f.txt",mode='r',encoding='utf8')
  
  for i in range(4):
      lineText=f.readline()
      print(lineText)
  
  f.close()
  </code></pre>
