title: Multiline file read in Python
body: <p>I am looking for a method in Python which can read multiple lines from a file(10 lines at a time). I have already looked into <code>readlines(sizehint)</code>, I tried to pass value 10 but doesn't read only 10 lines. It actually reads till end of the file(I have tried on the small file). Each line is 11 bytes long and each read  should fetch me 10 lines each time. If less than 10 lines are found then return only those lines. My actual file contains more than 150K lines.</p>
  
  <p>Any idea how I can achieve this?</p>
