我需要帮助。我马上就会告诉你代码。但首先，我将概述我要做的事情。这是一个程序，可以帮助我搜索Youtube最近的歌曲。
基本上，它需要一个文本文件并使用该数据在Youtube中搜索文本文件中的每个项目。我使用了readlines，然后通过制表符拆分它们。我正在使用的文本文件采用以下格式：
Track_Number [tab] Song_Title [tab] Artist [tab] Label - 进一步查看全文文件
文本文件示例Top 100 1 [tab] Lanterns [tab] Birds Of Tokyo [tab] CAP / EMI
2 [tab]当我是你的男人[tab] Bruno Mars [tab] ATL / WMA
3 [tab] Ho Hey The Lumineers [tab] INERTIA
4 [tab]在你的美丽[tab]下面Labrinth ft.Emeli Sande [tab] SME
5 [tab] Just Give Me A Reason [tab] Pink ft.Nate Ruess [tab] SME

def SearchAndBuild(keywords):

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()
对所有打印感到抱歉。那些是出于测试目的。如果你检查函数SearchAndBuild，你会看到我遇到问题的地方。我正在尝试使用由SongsFromFile设置的songList，然后使用该数据创建另一个包含歌曲标题和歌曲URL的列表列表。起初我尝试了“范围（0,99）中的songEntry”，但这使得索引超出了范围。我怀疑这是Youtube如何设置他们的api，所以我将其改为“songEntry in range（0,25）”
这似乎已经修复了超出范围的异常。这是Youtube api还是我错过了什么。我只是好奇为什么它迫使我分解我的查询。我是否必须再设置三个for循环才能构建所有100个项目？有没有更好的办法？
显然，这是一项正在进行中的工作。我可能做了很多愚蠢的事情并且错过了简单的解决方案。为什么我使用范围，为什么我使用列表而不是字典？如果你看到我在这里做的很荒谬，请让我知道并解释更好的方法。
此致 约什
好的，所以我似乎已经修好了。我最初是对的。是。有更好的方法来做到这一点。然而，问题是Youtube的API，就像我最初怀疑的那样。查询的最大结果变量默认设置为25。我试图查询100.这就是我超出范围的原因。咨询Youtube API应该是我的第一个想法。这是一个很容易解决的问题;但是，不要指望它现在做得多。这是一项正在进行中的工作。最后，我将使用它在Youtube上查找我正在收集的数据库中的歌曲。
像我说的那样。这个程序还没有做任何有意义的事情。我有更多的代码要添加。在任何情况下，我都应该记录下来，以防其他人遇到与Google Python Youtube API类似的搜索查询问题。请记住，如果你不断超出范围，Youtube限制quires为50，默认设置为25。你必须以某种方式解决这个问题。非常感谢HoopDady的评论让我重回正轨。

这里是我打算使用webbrowser打开歌曲中包含的Youtube网址的地方。显然，我不想同时打开10多个网页。所以我会使用一个循环然后在遇到某些条件时爆发，或者只是询问何时进入下一个项目等等。不过我会在以后想出来。
