如何使用Python根据日期和术语从Pubmed检索信息？

import requests
from bs4 import BeautifulSoup

base_url = "https://pubmed.ncbi.nlm.nih.gov/"
search_term = "your_search_term"  # 替换为你要搜索的术语
start_date = "yyyy/mm/dd"  # 替换为你要搜索的起始日期
end_date = "yyyy/mm/dd"  # 替换为你要搜索的结束日期
url = base_url + "?term=" + search_term + "&filter=datesearch.y_" + start_date + ":" + end_date

response = requests.get(url)
soup = BeautifulSoup(response.text, "html.parser")

articles = soup.find_all("article")  # 找到所有文章
for article in articles:
    title = article.find("a", class_="docsum-title").text  # 提取文章标题
    authors = article.find("span", class_="docsum-authors").text  # 提取作者信息
    journal = article.find("span", class_="docsum-journal-citation").text  # 提取期刊信息
    abstract = article.find("div", class_="docsum-content").text  # 提取摘要信息
    print("Title:", title)
    print("Authors:", authors)
    print("Journal:", journal)
    print("Abstract:", abstract)
    print("------")
