所以我有一个叫做的课Vertex.
class Vertex:
'''
This class is the vertex class. It represents a vertex.
'''
def __init__(self, label):
self.label = label
self.neighbours = []
def __str__(self):
return("Vertex "+str(self.label)+":"+str(self.neighbours))

我想打印这个类的对象列表,如下所示:
x = [Vertex(1), Vertex(2)]
print x

但它显示我这样的输出:
[<__main__.Vertex instance at 0xb76ed84c>, <__main__.Vertex instance at 0xb76ed86c>]

实际上,我想打印Vertex.label每个对象的值.有什么办法吗?
