Since Python 3.3, you can force the normal
print()function to flush without the need to use
sys.stdout.flush(); just set the
flushkeyword argument to
True. From the documentation:
print(*objects, sep=' ', end=' ', file=sys.stdout, flush=False)
Whether output is buffered is usually determined by file, but if the flush keyword argument is true, the stream is forcibly flushed.
