python string to list

Question

即使它看起来很简单，我也无法解决这个问题。

我在作者出版物条目存储这样的txt文件刮数据库：

['Radoslav Bajus'],[['Economic Annals-XXI', '2016-06-21'], ['Actual Problems of Economics', '2016-01-01'], ['Actual Problems of Economics', '2015-01-01'], ['Actual Problems of Economics', '2015-01-01'], ['Accounting Reform in Transition and Developing Economies', '2009-12-01']] 

我最初是通过列表旨在循环。但是，当我读txt我最后：

"['Alena Andrejovská'],[['Economic Annals-XXI', '2016-10-10'], ['Journal of Applied Economic Sciences', '2016-09-01'], ['Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis', '2016-01-01'], ['Agris On-line Papers in Economics and Informatics', '2016-01-01'], ['Actual Problems of Economics', '2016-01-01'], ['Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis', '2015-01-01'], ['Actual Problems of Economics', '2015-01-01'], ['Journal of Applied Economic Sciences', '2015-01-01'], ['Journal of Applied Economic Sciences', '2014-01-01'], ['Journal of Applied Economic Sciences', '2013-01-01']]" 

有没有方法来读取引号和字符串格式？ 我使用的代码如下：

fh = open('results_publications.txt', encoding = "utf8") 
    lst = [] 
    for line in fh: 
     lst.append(line.strip()) 

UPD好吧，抱歉没有说清楚。我有一个.txt文件，其中有以下由/ n分隔的条目（请参见下面的三个条目）。

['Alena Andrejovská'],[['Economic Annals-XXI', '2016-10-10'], ['Journal of Applied Economic Sciences', '2016-09-01'], ['Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis', '2016-01-01'], ['Agris On-line Papers in Economics and Informatics', '2016-01-01'], ['Actual Problems of Economics', '2016-01-01'], ['Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis', '2015-01-01'], ['Actual Problems of Economics', '2015-01-01'], ['Journal of Applied Economic Sciences', '2015-01-01'], ['Journal of Applied Economic Sciences', '2014-01-01'], ['Journal of Applied Economic Sciences', '2013-01-01']] 
['Radoslav Bajus'],[['Economic Annals-XXI', '2016-06-21'], ['Actual Problems of Economics', '2016-01-01'], ['Actual Problems of Economics', '2015-01-01'], ['Actual Problems of Economics', '2015-01-01'], ['Accounting Reform in Transition and Developing Economies', '2009-12-01']] 
['Ľudmila Bartóková'],[['Journal of Applied Economic Sciences', '2016-03-01'], ['E a M: Ekonomie a Management', '2015-01-01'], ['Journal of Applied Economic Sciences', '2013-01-01'], ['12th International Multidisciplinary Scientific GeoConference and EXPO - Modern Management of Mine Producing, Geology and Environmental Protection, SGEM 2012', '2012-12-01'], ['Journal of Applied Economic Sciences', '2012-12-01'], ['E a M: Ekonomie a Management', '2010-06-21']] 

我想将此txt文件读入列表中以便稍后能够循环访问。但是当你读取txt文件时，它会将每个条目转换为字符串并放入“”。我想弄清楚如何将它转换为列表列表，而不是字符串列表。

您可以从一个字符串转换回Python的数据，如

import ast 

data_string = "['Alena Andrejovská'],[['Economic Annals-XXI', '2016-10-10'], ['Journal of Applied Economic Sciences', '2016-09-01'], ['Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis', '2016-01-01'], ['Agris On-line Papers in Economics and Informatics', '2016-01-01'], ['Actual Problems of Economics', '2016-01-01'], ['Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis', '2015-01-01'], ['Actual Problems of Economics', '2015-01-01'], ['Journal of Applied Economic Sciences', '2015-01-01'], ['Journal of Applied Economic Sciences', '2014-01-01'], ['Journal of Applied Economic Sciences', '2013-01-01']]" 

data = ast.literal_eval(data_string)
