def example_generator(n):
    """Generators have a ``Yields`` section instead of a ``Returns`` section.
    Args:
      n (int): The upper limit of the range to generate, from 0 to `n` - 1
    Yields:
      int: The next number in the range of 0 to `n` - 1
    Examples:
      Examples should be written in doctest format, and should illustrate how
      to use the function.

for i in range(n):
    pass
Is there a reST Python docstring field for yields?
