I'm new to beautifulsoup and didn't find good example to make this happen. I want to have some example to follow.

推荐答案

想法是在table#productDetailsTable div.content ul li 打印:

{
    u'Age Range': u'9 - 12 years',
    u'Amazon Best Sellers Rank': u'#1,440 in Books (',
    u'Average Customer Review': u'',
    u'Grade Level': u'4 - 7',
    u'ISBN-10': u'0439136369',
    u'ISBN-13': u'978-0439136365',
    u'Language': u'English',
    u'Lexile Measure': u'880L',
    u'Mass Market Paperback': u'448 pages',
    u'Product Dimensions': u'1.2 x 5.2 x 7.8 inches',
    u'Publisher': u'Scholastic Paperbacks (September 11, 2001)',
    u'Series': u'Harry Potter (Book 3)',
    u'Shipping Weight': u'11.2 ounces ('
}

请注意，一旦碰到AttributeError，我们就会中断循环.发生在li元素内没有更多粗体的文本之后.

Note that we are breaking the loop as soon as we hit an AttributeError. It happens on after there is no more bold text inside the li element.
