Run pyupgrade to clean up Python 2 syntaxes
Update all .py source files by $ pyupgrade --py3-only $(git ls-files | grep ".py$") to modernize the code according to Python 3 syntaxes. pep8 errors are fixed by $ autopep8 --select=E127,E128,E501 --max-line-length 79 -r \ --in-place tooz Also add the pyupgrade hook to pre-commit to avoid merging additional Python 2 syntaxes.
