# 或者: from Bio.Pathway.Rep.MultiGraph import nodes [as 别名]
def testNodes(self):
a = MultiGraph()
self.assertEqual(a.nodes(), [], "default graph not empty")

self.assertEqual(a.nodes(), ['a'], "duplicate node added")
a.add_node('b')
l = a.nodes()
l.sort()
self.assertEqual(l, ['a', 'b'], "second node not added")示例2: Network
