Python Youtube API搜索超出范围

Question

我需要帮助。我马上给你看代码。但首先我要概述一下我要做的事情。这是一个帮助我在Youtube上搜索最新歌曲的程序。在

本质上，它使用一个文本文件并使用这些数据在Youtube上搜索文本文件中的每一项。我使用readline，然后用制表符将它们分开。我使用的文本文件格式如下：

曲目编号[tab]歌曲名称[tab]艺术家[tab]标签 --进一步查看全文文件

---

文本文件前100名示例
1[tab]灯笼[tab]东京鸟[tab]CAP/EMI

当我是你的人时布鲁诺·马尔斯ATL/WMA

3[tab]嘿，发光二极管的惯性

4[tab]在您美丽的[tab]Labrinth ft.Emeli Sande[tab]SME下方

5[tab]给我一个理由[tab]Pink ft.Nate Ruess[tab]SME

这是密码

import gdata.youtube
import gdata.youtube.service
import webbrowser 
topSongVersion = "0.1"
yt_service = gdata.youtube.service.YouTubeService()


songListRaw = [] 
songList = []
videoData = [] 


def SearchAndBuild(keywords):
  videoData = []
  query = gdata.youtube.service.YouTubeVideoQuery()

  for songEntry in range(0, 25):
    query.orderby = 'viewCount'
    query.racy = 'include'    
    query.vq = keywords[songEntry][0] + ' ' + keywords[songEntry][-1]    
    feed = yt_service.YouTubeQuery(query)

    #videoData.append(feed.entry[songEntry].media.title.text) 
    #videoData.append(feed.entry[songEntry].GetSwfUrl())
    videoData.append(query.vq + ' ' + feed.entry[songEntry].GetSwfUrl())
    print songEntry, query.vq, feed.entry[songEntry].GetSwfUrl() 
  print(videoData[24])

 #print videoData

def SongsFromFile():
  f = open('top100.txt')
  songData = f.readlines() 
  f.close() 
  for songRaw in range(1,101):
    songListRaw.append(songData[songRaw].split('\t'))  
  for songEntry in range(0,100):
    songList.append(songListRaw[songEntry][1:-1])

  SearchAndBuild(songList)

#  print(songList[0]) 
#  print(songList[1])
#  print(testSearch[0])
#  print(testSearch[1])

SongsFromFile()

抱歉，打印太多了。这些是为了测试目的。如果你检查SearchAndBuild函数，你会发现我哪里出了问题。我试图获取由SongsFromFile设置的歌曲列表，然后使用该数据创建另一个包含歌曲标题和歌曲URL的列表。一开始我尝试了“songEntry in range（0，99）”，但这使索引一直超出范围。我怀疑这是Youtube设置api的方式，所以我把它改为“范围内的songEntry（0，25）”

这似乎已经修复了超出范围的异常。要么是Youtube api，要么是我遗漏了什么。我只是好奇为什么它会迫使我分开我的查询。我需要再设置三个for循环来建立100个项目吗？有更好的方法吗？在

显然，这是一个正在进行的工作。我可能做了很多蠢事，却错过了简单的解决方案。为什么我用范围，为什么我用列表而不是dict？如果你看到我在这里做的荒唐事，请告诉我并解释更好的方法。在

真诚的， 乔希

好吧，看来我自己已经修好了。起初我是对的。对。有更好的方法来做到这一点。然而，问题出在Youtube的API上，就像我最初怀疑的那样。默认情况下，最大查询结果变量设置为25。我想查询100。这就是为什么我会越界。我首先想到的应该是查阅Youtube API。解决这么多麻烦是件很容易的事；不过，现在不要指望它能起到多大作用。这是一项正在进行的工作。最终，我会用它在Youtube上找到我正在收集的数据库中的歌曲。在

就像我说的。这个程序还没有做任何有意义的事情。我还有很多代码要添加。无论如何，我应该把这一点记录下来，以防其他人在使用googlepythonyoutube API进行搜索查询时遇到类似的问题。记住这一点，如果你一直抛出超出范围，Youtube的限制是50，默认设置为25。你得设法解决这个问题。在

非常感谢hoopadady的评论，让我重回正轨。在

以下是修改后的代码：

我打算在这里使用webbrowser打开包含在歌曲中的Youtube网址。显然，我不想同时打开10多个网页。所以我将使用一个循环，然后在满足某些条件时中断，或者只是询问何时转到下一个项目，等等，不过，我稍后会解决这个问题。在
