如何删除嵌套在其他双引号正则表达式中的双引号

Question

我正在尝试使用 json.loads 加载使用 Beautiful Soup 收集的数据。 但是，我使用的数据存在一个问题，即某些字段在字段中包含双引号。 例子：

"rComments":"He is a very easy grader, but gets boring occasionally. I wish he would quit saying "Without further ado..." Cancer Bio is a great class because there is a different lecturer each time."

这导致以下错误：

JSONDecodeError: Expecting ',' delimiter: line 1 column 3556 (char 3555)

有没有办法使用正则表达式或其他方法用单引号/无引号替换“不用多说...”周围的双引号？ 我需要保留其他双引号，因为 JSON 需要这些

这是我的代码的副本。 对于任何具有嵌套双引号的 Prof ID，它都会失败。

# Make Request
url1 = 'https://www.ratemyprofessors.com/paginate/professors/ratings?tid={}&filter=&courseCode=&page=1'.format(124880)
page1 = requests.get(url1)
soup1 = BeautifulSoup(page1.text, "html.parser")
soup1 = str(soup1)

# Remove Double Quotes in Comments
soup1 = re.sub(r'(?:[\b\s\:]\".*)(?:.*)(\")(?:.*\")', '', soup1)

# Create Dictionary
Dict1 = json.loads(soup1)

我也尝试了下面的正则表达式，但它也没有用。

:r"(\".*?)\"(.*?)\"(.*\")

作为参考，这是 repr(soup1) 返回的内容。

看起来你正在下载的 API 返回 JSON，而不是 HTML，所以你不需要用 BeautifulSoup 解析它。你可以简单地执行以下操作：

import requests


url = 'https://www.ratemyprofessors.com/paginate/professors/ratings?tid={}&filter=&courseCode=&page=1'.format(124880)
page = requests.get(url)
page.json()
