The answer to your question depends on what version of Python you are
running. Give python version and platform to any question when you
don't _know_ they are irrelevant.
If you want an answer without any other input, try this:
The simplest way to solve this for the moment is (re)defining
xreadlines:
def xreadlines(source):
for line in iter(src.readline, ''):
yield line
