Python MultiGraph.set_color Examples

Example #1

graph1 = MultiGraph()

for i in range(1, 31, 1):
    graph1.add_vertex(i)
    graph1._positions[i] = (0, 0)

##########
for i in range(1, 15, 1):
    e_id = graph1.add_edge(i, i + 1)
    edge = graph1.get_edge(e_id)
    edge.color = i % 2 + 1

e_id = graph1.add_edge(1, 15)
edge = graph1.get_edge(e_id)
graph1.set_color(e_id, 1, 1)
graph1.set_color(e_id, 15, 2)

for i in range(16, 30, 1):
    e_id = graph1.add_edge(i, i + 1)
    edge = graph1.get_edge(e_id)
    edge.color = i % 2 + 1

e_id = graph1.add_edge(16, 30)
edge = graph1.get_edge(e_id)
graph1.set_color(e_id, 16, 2)
graph1.set_color(e_id, 30, 1)
