我很难使用 eye3d python 模块返回 mp3 的播放时间......我可以使用以下内容检索标签信息等：

import eyed3

def getInfo():
    srcPath = r'C:\aaa'
    os.chdir(srcPath) #change working directory

    inf = eyed3.core.load('test.mp3')

    print inf.tag.album

但无法掌握如何使用此处看到的“class eyed3.core.AudioInfo [source]”（http://eyed3.nicfit.net/api/eyed3.html）来获得播放时间。我只是想返回歌曲的长度（然后最终遍历播放列表以找到播放列表的播放时间）。

谢谢

很简单：

af = eyed3.load('my_mp3_file.mp3')
duration = af.info.time_secs

不确定这是否记录在任何地方，但我能够通过在 iPython 中查看内容来解决这个问题。

如果您更喜欢单线，您也可以这样做：

duration = eyed3.load('my_mp3_file.mp3').info.time_secs

我应该注意，对于可变比特率 mp3，这个值可能相差甚远。这是因为它通过对 mp3 帧进行采样来确定长度，并对整个音轨进行猜测。对于可变比特率，这意味着如果轨道开头的音频不具有代表性，则猜测会很差。

@user1526973 @mlissner 的回答是正确的，我受到启发来创建它，这是我的工作产品版本。

@twigg 是的，您可以获得比特率。
