I wrote the below code

    if (not len(G)):
        raise nx.NetworkXException('An    empty    graph    cannot    be    drawn.')
    import pygraphviz
    attrs = ['edge', 'node', 'graph']
    for attr in attrs:
        if (attr not in G.graph):
            G.graph[attr] = {}
    edge_attrs = {'fontsize': '10'}
    node_attrs = {'style': 'filled', 'fillcolor': '#0000FF40', 'height': '0.75', 'width': '0.75', 'shape': 'circle'}
    graph_attrs = {}
    def update_attrs(which, attrs):
        added = []
        for (k, v) in attrs.items():
            if (k not in G.graph[which]):
                G.graph[which][k] = v
                added.append(k)
    def clean_attrs(which, added):
        for attr in added:
            del G.graph[which][attr]
        if (not G.graph[which]):
            del G.graph[which]
    update_attrs('edge', edge_attrs)
    update_attrs('node', node_attrs)
    update_attrs('graph', graph_attrs)
    A = to_agraph(G)
    clean_attrs('edge', edge_attrs)
    clean_attrs('node', node_attrs)
    clean_attrs('graph', graph_attrs)
    if (edgelabel is not None):
        if (not hasattr(edgelabel, '__call__')):
            def func(data):
                return ''.join(['        ', str(data[edgelabel]), '        '])
        else:

        else:

                edge = A.get_edge(u, v)
                edge.attr['label'] = str(func(data))
    if (path is None):
        ext = 'png'
        if suffix:
            suffix = ('_%s.%s' % (suffix, ext))
        else:
            suffix = ('.%s' % (ext,))
        path = tempfile.NamedTemporaryFile(suffix=suffix, delete=False)
    else:
        pass
    display_pygraphviz(A, path=path, prog=prog, args=args)
    return (path.name, A)

What's a good function header?
 Write me a Python program to fix = ('_%s?

#Here is Python program to fix = ('_%s.
