Python 如何拆分字符串并将所有拆分内容添加到一个长列中？

我有一个一列多行的数据框。每一行包含一首歌曲的歌词，歌词行由“\n”分隔，到目前为止，我得到的是

with open('Lyrics_Pavement.json') as json_data:
data = json.load(json_data)
df = pd.DataFrame(data['songs'])
df1 = df.lyrics.str.split(pat="\n")

然后，df1包含一个1列数据帧，其中的歌词已被删除，\n并被“[]”包围

1    [It's the shouting, it's the shouting, It's the Dutchman, it's the Dutchman shout, Get it away, I don't need your shaft, It's the shouting, it's the shouting, It's the shouting, it's the Dutchman shout, Give it away, I don't need your shaft, (yes I do), It's the shouting, it's the shouting, It's the shouting, it's the Dutchman shout, Get it away, I don't need your shaft] 

这是第1行的一个示例。我如何使数据显示为这样：

It's the shouting,
It's the shouting,
It's the dutchman

等等。上面的每一行都是数据帧的一行。然后，对于第2行，将这些相同的歌词附加到该数据帧

谢谢

因此我可以替换“\n”上的拆分。那么我会使用for循环来附加每首额外的歌曲吗？第0行恰好是一首器乐歌曲

edit2:这给了我AttributeError:“list”对象没有属性“split”

with open('Lyrics_Pavement.json') as json_data:
    data = json.load(json_data)

df = pd.DataFrame(data['songs'])


df1 = df.lyrics.str.split(pat="\n")

s = df1.loc[1]
lines = [i.strip() for i in s[1:-1].split(',')]
df2 = pd.DataFrame(lines)

print(df2)

---

Edit3：上面的代码确实有效，我所指的数据帧是错误的。以下任一解决方案都有效，我将逗号上的分隔改为“\n”。谢谢大家

我从你的帖子中得知，

df1

中的歌词只是一个长字符串，而不是实际的

列表

？如果是这样的话，那么我只需要使用内置的string方法

将这个字符串用逗号拆分，然后重新组装成一个数据帧：

s = "[It's the shouting, it's the shouting, It's the Dutchman, it's the Dutchman shout, Get it away, I don't need your shaft, It's the shouting, it's the shouting, It's the shouting, it's the Dutchman shout, Give it away, I don't need your shaft, (yes I do), It's the shouting, it's the shouting, It's the shouting, it's the Dutchman shout, Get it away, I don't need your shaft]"

lines = [i.strip() for i in s[1:-1].split(',')]
df = pd.DataFrame(lines)

输出：

                          0
0         It's the shouting
1         it's the shouting
2         It's the Dutchman
3   it's the Dutchman shout
4               Get it away
5   I don't need your shaft
6         It's the shouting
7         it's the shouting
8         It's the shouting
9   it's the Dutchman shout
10             Give it away
11  I don't need your shaft
12               (yes I do)
13        It's the shouting
14        it's the shouting
15        It's the shouting
16  it's the Dutchman shout
17              Get it away
18  I don't need your shaft


s[1:-1]
省略括号
.split（'，'）
以逗号分隔
.strip（）
删除多余空格

如果您知道每首歌词之间总是只有一个逗号+一个空格，那么您也可以执行
lines=s[1:-1]。拆分（'，'）

如果您的完整歌词是
df1
的一部分，您只需
loc
（或w/e）访问字符串并按照此答案进行操作。
尝试：

import pandas as pd

longstring = '''It's the shouting, it's the shouting, It's the Dutchman, it's the Dutchman shout, Get it away, I don't need your shaft, It's the shouting, it's the shouting, It's the shouting, it's the Dutchman shout, Give it away, I don't need your shaft, (yes I do), It's the shouting, it's the shouting, It's the shouting, it's the Dutchman shout, Get it away, I don't need your shaft'''


splitstring = [e.strip()+"," for e in longstring.split(",")]
splitstring[-1] = splitstring[-1].replace(",","")
df1 = pd.DataFrame(splitstring)
print(df1)  


#                           0
#0         It's the shouting,
#1         it's the shouting,
#2         It's the Dutchman,
#3   it's the Dutchman shout,
#4               Get it away,
#5   I don't need your shaft,
#6         It's the shouting,
#7         it's the shouting,
#8         It's the shouting,
#9   it's the Dutchman shout,
#10             Give it away,
#11  I don't need your shaft,
#12               (yes I do),
#13        It's the shouting,
#14        it's the shouting,
#15        It's the shouting,
#16  it's the Dutchman shout,
#17              Get it away,
#18   I don't need your shaft

啊，与我的答案类似，我在主要帖子后面添加了逗号，以使文章更加清晰。当我试着这样做时，我得到了一个错误AttributeError:“list”对象没有属性“split”，我把我正在使用的代码放在主后处理中。事实上，我意识到我做错了什么，包括这个和其他解决方案。谢谢你们两位！
df1 = df.lyrics.str.split(pat="\n").explode()
