The title suggests you can write Python and get LaTeX, but it's "converting ordinary expressions into mathTeX". I was expecting something like this:

    def section(name='Abstract'):
      print('We present a novel new way...')
      fig(path='my.png', width='90%')

Anyway, still a cool project! I might make use of this in the future. Just remarking that the title hints at something else -- at least to me.
