示例1: AudioFile

# 或者: from mutagen.File import __getitem__ [as 别名]
class AudioFile(MutableMapping):
"""A simple class just for tag editing.
No internal mutagen tags are exposed, or filenames or anything. So
calling clear() won't destroy the filename field or things like
that. Use it like a dict, then .write() it to commit the changes.
When saving, tags that cannot be saved by the file format will be
skipped with a debug message, since this is a common occurrance
with MP3/M4A.
Optional argument blacklist is a list of regexps matching
non-transferrable tags. They will effectively be hidden, nether
settable nor gettable.
Or grab the actual underlying mutagen format object from the
.data field and get your hands dirty.
