Looks interesting, you might want to consider running your code
through some of the existing Python checkers such as flake8 and pylint.
If you want this to be generally available in repos, best to follow the language conventions

For example flake8 noticed:
 $ flake8 --max-line-length=120 ./tools/net/ynl/samples/ynl.py 
./tools/net/ynl/samples/ynl.py:251:55: F821 undefined name 'file_name'

Thanks! I'll make sure to check flake8 (pylint is too noisy for me :()
