无法使用biopython从pubmed检索文件

Question

我正在使用此脚本从pubmed获取有关新冠肺炎的数据

from Bio import Entrez
    def search(query):
        Entrez.email = 'your.email@example.com'
        handle = Entrez.esearch(db='pubmed', 
                                sort='relevance', 
                                retmax='20',
                                retmode='xml', 
                                term=query)
        results = Entrez.read(handle)
        return results
    
    def fetch_details(id_list):
        ids = ','.join(id_list)
        Entrez.email = 'your.email@example.com'
        handle = Entrez.efetch(db='pubmed',
                               retmode='xml',
                               id=ids)
        results = Entrez.read(handle)
        return results
    
    if __name__ == '__main__':
        results = search('covid-19')
        id_list = results['IdList']
        papers = fetch_details(id_list)
        for i, paper in enumerate(papers['PubmedArticle']):
            print("{}) {}".format(i+1, paper['MedlineCitation']['Article']['ArticleTitle']))

我在控制台上得到了结果，但我想要的是自动下载文件，如XML文件或文本文件的文章，任何建议，请如何做我谷歌它，但没有找到

您可以在末尾添加此代码以保存到JSON文件中

#write to file 
import json
with open('file.json', 'w') as json_file:
      json.dump(papers, json_file)
