bug - easy.py throws ValueError

[jisungk]

easy.py throws an error, even on standard datasets (e.g., iris):

Traceback (most recent call last):
  File "easy.py", line 63, in <module>
    c,g,rate = map(float,last_line.split())
ValueError: need more than 0 values to unpack

This was observed in Windows but has been reported for other OS's elsewhere.
