No, because C and C++ libraries such as Open Babel have to link to the appropriate version of libpython. Noel's question is "why not use Python 3.5" instead of 3.6? Sierra doesn't come with Python 3.6, so why did you install that version? A new release that will be compatible with Python 3.6 will be released - but in the meantime, I'm using Python 3.5 just fine on my MacBook.
