Answer 1

日志报告IndentationError，因此代码中的缩进有问题：具体来说，for循环过度缩进，for语句应该是与bsObj作业处于同一级别。

您还需要使变量名称保持一致（link | links）并使用attrs属性，而不是attr。固定代码如下（未经测试）。

@route('/')
@view("index_template")
def index():
    html = urlopen("https://en.wikipedia.org/wiki/Kevin_Bacon")
    internalLinks=[]
    bsObj = BeautifulSoup(html, "html.parser")
    for link in bsObj.findAll("a"):
        if 'href' in link.attrs:
            internalLinks.append(link.attrs['href'])
    return dict(internalLinks=internalLinks)

我想将数组传递给瓶子模板并显示其内容
