python string to list

Question

即使它看起來很簡單，我也無法解決這個問題。

我在作者出版物條目存儲這樣的txt文件刮數據庫：

['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']] 

我最初是通過列表旨在循環。但是，當我讀txt我最後：

"['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']]" 

有沒有方法來讀取引號和字符串格式？ 我使用的代碼如下：

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

UPD好吧，抱歉沒有說清楚。我有一個.txt文件，其中有以下由/ n分隔的條目（請參見下面的三個條目）。

['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']] 

我想將此txt文件讀入列表中以便稍後能夠循環訪問。但是當你讀取txt文件時，它會將每個條目轉換爲字符串並放入「」。我想弄清楚如何將它轉換爲列表列表，而不是字符串列表。

您可以從一個字符串轉換回Python的數據，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)
