我有一个名为 tropical.txt 的文本文件，它有多个列表，每个列表由一个新行分隔。注意逗号是由空格包围的。

 space here and space here
['papaya' , 'mangosteen' , 'banana']
['coconut' , 'mango']
['mangosteen' , 'papaya']

我尝试了以下代码

import pandas as pd
df = pd.read_csv('tropical.txt', sep='\n', header=None, engine = 'python')
df

这给了我

ValueError: Specified \n as separator or delimiter. This forces the python engine which does not accept a line terminator. Hence it is not allowed to use the line terminator as separator.

如果我就这么做

import pandas as pd
df = pd.read_csv('tropical.txt', header= None, engine = 'python')
df

输出不是我想要的

         0           1             2
0   ['papaya'   'mangosteen'    'banana']
1   []               None        None
2   ['coconut'      'mango']     None
3   ['mangosteen'   'papaya']    None

我期待着

                        0   
0   [papaya,mangosteen,banana]
1   []  
2   [coconut,mango] 
3   [mangosteen,papaya]

有什么建议吗？
