  videos.append(data)                                                                                                                                     
print json.dumps(videos) # this code cause problem

我将'dict'插入'list'然后调用json.dumps()但是,出现错误错误messege是'dict'对象没有属性'dumps'

什么是问题？,我该如何解决这个问题？

我想获取nextPageToken下面的youtube数据api是我的代码，我想获取所有nextpageTokens。在循环中，我想重新分配nextPageToken
