bipfont.py unpack is not working

[Stefan1200-de]

I tried to unpack different amazfit font files, but bipfont.py use an unsupported operand:

bipfont.py unpack ISOCPEUR.ft ('Unpacking', 'ISOCPEUR.ft') Traceback (most recent call last): File "D:\Downloads\Amazfit Bip\AmazfitBip-tools-master\bipfont.py", line 148, in <module> unpackFont(sys.argv[2]) File "D:\Downloads\Amazfit Bip\AmazfitBip-tools-master\bipfont.py", line 33, in unpackFont num_ranges = (header[0x21] << 8) + header[0x20] TypeError: unsupported operand type(s) for <<: 'str' and 'int'

Using Python 2.7, Pillow 5.3.0 and the newest pathlib library for AMD64 on Windows 10. What can I do here to fix this issue?

Update: The amazfitbip tools readme told me that Python 2.7 is required. But it is not working. It seems that Python 3+ is required, because with Python 3.6.6 it is working. So the only issue here is updating the system requirements in the readme file.

Yes, script reads ranges (eg. 253) and use the only last one. There is really something wrong.
