Parsing BibTeX citation format with Python

What is the best way in python to parse these results? I have tried regex but can't get it to work. I am looking for a dictionary of title, author etc as keys.

@article{perry2000epidemiological,
  title={An epidemiological study to establish the prevalence of urinary symptoms and felt need in the community: the Leicestershire MRC Incontinence Study},
  author={Perry, Sarah and Shaw, Christine and Assassa, Philip and Dallosso, Helen and Williams, Kate and Brittain, Katherine R and Mensah, Fiona and Smith, Nigel and Clarke, Michael and Jagger, Carol and others},
  journal={Journal of public health},
  volume={22},
  number={3},
  pages={427--434},
  year={2000},
  publisher={Oxford University Press}
}

Solution

You might be looking for a BibTeX-parser: https://bibtexparser.readthedocs.io/en/master/

Source: https://bibtexparser.readthedocs.io/en/master/tutorial.html#step-0-vocabulary

Input/Create bibtex file:

bibtex = """@ARTICLE{Cesar2013,
  author = {Jean César},
  title = {An amazing title},
  year = {2013},
  month = jan,
  volume = {12},
  pages = {12--23},
  journal = {Nice Journal},
  abstract = {This is an abstract. This line should be long enough to test
     multilines...},
  comments = {A comment},
  keywords = {keyword1, keyword2}
}
"""

with open('bibtex.bib', 'w') as bibfile:
    bibfile.write(bibtex)

Parse it:

import bibtexparser

with open('bibtex.bib') as bibtex_file:
    bib_database = bibtexparser.load(bibtex_file)

print(bib_database.entries)

Output:

[{'journal': 'Nice Journal',
  'comments': 'A comment',
  'pages': '12--23',
  'month': 'jan',
  'abstract': 'This is an abstract. This line should be long enough to test\nmultilines...',
  'title': 'An amazing title',
  'year': '2013',
  'volume': '12',
  'ID': 'Cesar2013',
  'author': 'Jean César',
  'keyword': 'keyword1, keyword2',
  'ENTRYTYPE': 'article'}]
