    """
    Build extension module from a Fortran 77 source string with f2py.
    Parameters
    ----------
    source : str or bytes
        Fortran source of module / subroutine to compile
        .. versionchanged:: 1.16.0
           Accept str as well as bytes
    modulename : str, optional
        The name of the compiled python module
    extra_args : str or list, optional
        Additional parameters passed to f2py
        .. versionchanged:: 1.16.0
            A list of args may also be provided.
    verbose : bool, optional
        Print f2py output to screen
    source_fn : str, optional
        Name of the file where the fortran source is written.
        The default is to use a temporary file with the extension
        provided by the ``extension`` parameter
    extension : ``{'.f', '.f90'}``, optional
        Filename extension if `source_fn` is not provided.
        The extension tells which fortran standard is used.
        The default is ``.f``, which implies F77 standard.
        .. versionadded:: 1.11.0
    full_output : bool, optional
        If True, return a `subprocess.CompletedProcess` containing
        the stdout and stderr of the compile process, instead of just
        the status code.
        .. versionadded:: 1.20.0
    Returns
    -------
    result : int or `subprocess.CompletedProcess`
        0 on success, or a `subprocess.CompletedProcess` if
        ``full_output=True``
    Examples
    --------
