Question

我有一个作者和书籍列表，并且正在使用API来检索它们各自的描述和等级。我无法迭代列表并将说明存储在新列表中。

Goodreads API使我有机会查找书籍的信息，以准确性发送书名和作者，或者只发送书名。我想要的是：

环绕标题和作者的列表，获取第一标题和第一作者，然后尝试检索描述并将其保存在第三列表中。
如果找不到，请尝试仅使用标题检索描述并将其保存到列表中。
如果尚未找到，请添加标准错误消息。

我尝试了下面的代码，但无法迭代整个列表并保存结果。

#Running the API with author's name and book's title
book_url_w_author = 'https://www.goodreads.com/book/title.xml?author='+edit_authors[0]+'&key='+api_key+'&title='+edit_titles[0]

#Running the API with only book's title
book_url_n_author = 'https://www.goodreads.com/book/title.xml?'+'&key='+api_key+'&title='+edit_titles[0]

# parse book url with author
html_n_author = requests.get(book_url_w_author).text
soup_n_author = BeautifulSoup(html_n_author, "html.parser")

# parse book url without author
html_n_author = requests.get(book_url_n_author).text
soup_n_author = BeautifulSoup(html_n_author, "html.parser")

#Retrieving the books' descriptions
description = []

try:
    #fetch description for url with author and title and add it to descriptions list
    for desc_w_author in soup_w_author.book.description:
        description.append(desc_w_author)
except:
    #fetch description for url with only title and add it to descriptions list
    for desc_n_author in soup_n_author.book.description:
        description.append(desc_n_author)
else:
    #return and inform that no description was found
    description.append('Description not found')

Expected:
description = [description1, description2, description3, ....]

try-except-else中的循环问题
