我想从“feed_entry”对象中提取的“作者姓名”。我尝试这样做:
print data.feed_entry.author.name
我得到的错误:
AttributeError: 'RepeatedCompositeFieldContainer' object has no attribute 'name'
我尝试了打印author对象,看看会发生什么。这是我得到的:
print u.feed_entry.author
[<spinn3rApi_pb2.Author object at 0x362e6d0>]
我该如何提取此作者的名字?
答
它看起来像u.feed_entry.author
是一个列表。请注意括号:
[<spinn3rApi_pb2.Author object at 0x362e6d0>]
这应该解决您的问题(假设你有至少一个作者):
print data.feed_entry.author[0].name
你'目录(数据)'得到什么? – Salem 2013-03-02 18:59:33
