我想用 } 替换所有逗号，但 "lyrics" 列中的逗号太多，我尝试使用正则表达式。
for i in range(0,len(dat)):
dat[i] = re.sub('(['"])," , '}',dat[i])
dat[i] = re.sub('(\])," , ']}',dat[i])

我使用的是@Wiktor Stribiżew 的解决方案。但我发现了一个新问题。有时这种模式也匹配歌词文本中的逗号，分割得比需要的多。
这是造成问题的行之一：
['A1_(group)', 'album: "The A List" (2000)', "Livin' The Dream", "\n\r\nWhere have you been all my life? \r\nWhere have you come from? \r\nIs this your first time too? \r\nIt's like I've known you in some other lifetime. \r\nWe're part of the great plan. \r\nLike two stars the shine.\n\n[Pre-Chorus:]\r\nI stood here watchin', while it only ever happened to friends. \r\nNow I don't have to pretend.\n\n[Chorus:]\r\nI can't believe we're living the dream\r\nWe're diggin that scene. \r\nWe finally made it through the fire. \r\nSomething 'bout you blows me away, like night over day. \r\nKissing the loneliness goodbye yeah.\n\r\nTrue love, true love. \r\nBaby could this be. \r\nTrue love, true love happenin' to me? \n\r\nI've been waiting for you all my life\r\nAnticipating with ever dream ever night. \r\nDestiny's moment we all share in time love is the message. \r\nAnd I know I've got mine¡-\n\n[Pre-Chorus]\n\n[Chorus]\n\r\nTrue love, true love. \r\nBaby could this be. \r\nTrue love, true love happenin' to me? \r\nTrue love, true love. \r\nBaby could this be. \r\nTrue love, true love happenin' to me?\n\n[Chorus]\n\n[Outro:]\r\nTrue love, true love.

Baby could this be. \r\nTrue love, true love happenin' to me?\n", 'London, United KingdomOslo, Norway', [], '1998–2002, 2009–present']
在这种情况下，有一些词，例如 watchin', 带有撇号和逗号。
我该如何解决？我很确定这需要不止一步，也许删除逗号？但是如果我这样做，我不知道要遵循什么模式来划分字符串..
可以使用str.replace()，这将用想要的字符替换所有字符。
你的情况
dat.replace(',', '}')
或者如果它是一个列表
[x.replace(',', '}') for x in dat]
您没有形成有效的字符串文字和无效的反向引用语法。而不是 </code>，你需要在 Python 中写 <code>。如果不想使用双反斜杠，请不要忘记使用原始字符串文字 (r'' = '\1').
一定要这样写
dat[i] = re.sub(r'''(['"]),''' , r'}',dat[i])
dat[i] = re.sub(r'''(\]),''' , r']}',dat[i])
