要列出的python字符串[重复]

Question

我想不出解决这个问题，即使它看起来很容易。

我在 txt 文件中有一个抓取的数据库，其中作者出版物的条目存储如下：

    ['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']]

我原本打算遍历列表。但是当我阅读 txt 时，我最终得到：

    "['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']]"

有没有办法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 好的，抱歉不清楚。我有一个 .txt 文件，其中有以下由 /n 分隔的条目（请参阅下面的三个条目）。

['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']]

我想将这个 txt 文件读入列表，以便以后能够循环浏览它。但是当您阅读 txt 文件时，它会将每个条目转换为字符串并放入“”。我试图弄清楚如何将其转换为列表列表，而不是字符串列表。

Answer 1

您可以将字符串转换回 Python 数据，例如

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)
