获取特定作者的所有href

您好，我正在尝试获取所有/ pubmed /编号，这些编号将我链接到特定作者的文章摘要。问题是，当我尝试这样做时，我只会一遍又一遍地获得相同的数字，直到for循环结束为止。

我要获取的href应当取自for in line in lines循环的输出（具体的href在输出示例中）。该循环似乎工作良好，但随后，“抽象中的抽象”循环仅重复相同的href。

任何建议或想法，我缺少或做错了什么。我对bs4没有太多的经验，所以我可能没有很好地使用该库。

#Obtain all the papers of a scientific author and write its abstract in a new file

    from bs4 import BeautifulSoup

    import re

    import requests

    url="https://www.ncbi.nlm.nih.gov/pubmed/?term=valvano"
    response = requests.get(url)



    soup = BeautifulSoup(response.content, 'lxml')


    lines = soup.find_all("div",{"class": "rslt"})

    authors= soup.find_all("p",{"class": "desc"})

    scientist=[]

    for author in authors:
            #print('\n', author.text)
        scientist.append(author.text)
    s=[]
    for i in scientist:
        L=i.split(',')
        s.append(L)          


    n=0

    for line in lines:

        if ' Valvano MA' in s[n] or 'Valvano MA' in s[n] :
            print('\n',line.text)
#part of one output:

            found = soup.find("a",{"class": "status_icon nohighlight"})
