Why buffer.py exmaple is not working with me?

[raghadalhelal]

$ python buffer.py 
Traceback (most recent call last):
  File "buffer.py", line 23, in <module>
    main()
  File "buffer.py", line 13, in main
    kind = filetype.guess(data)
  File "/home/myuser/.local/lib/python2.7/site-packages/filetype/filetype.py", line 28, in guess
    return match(obj) if obj else None
  File "/home/myuser/.local/lib/python2.7/site-packages/filetype/match.py", line 28, in match
    buf = get_bytes(obj)
  File "/home/myuser/.local/lib/python2.7/site-packages/filetype/utils.py", line 64, in get_bytes
    return get_signature_bytes(obj)
  File "/home/myuser/.local/lib/python2.7/site-packages/filetype/utils.py", line 17, in get_signature_bytes
    with open(path, 'rb') as fp:
IOError: [Errno 2] No such file or directory: 'HelloWorld\n'

I tried to use buffer.py on a text file but without success.
