Python从<a> tag

Question

I have a list of web-pages that I'm looping through. My goal is to get text from each of these web-pages IF there is something. I'm looking for certain -tag elements that have same className. First part (looping) is working perfectly but for some reason i'm getting only value [None] while printing this -tags text.

here is what i'm doing:

jotain = []
col = 3
for row, urls in enumerate(links):
    page = requests.get(urls)
    soup = BeautifulSoup(page.content, 'html.parser')
    sposti = soup.find('a', {'class' : '_contactLink_1i8pl_1'})
    jotain.append(sposti)
    print(jotain.text)

sheet.write(row, col, sposti)

It returns me: "AttributeError: 'list' object has no attribute 'text'"

And this is how the html looks like:

<a class="_contactLink_1i8pl_1" href="mailto:info@talligym.fi">info@talligym.fi</a>

Thanks for help in advance!

Answer 1

jotain是保存您的属性元素的列表，请尝试

jotain.append(sposti.text)
print(jotain)

编辑：通过打印变量“ sposti”来进行调试，检查是否确实要首先获取数据。

Answer 2

您要将在soup中找到的数据追加到列表jotain，而无需在列表中调用jotain.text，这就是您阅读在soup中找到的文本。您需要将文本部分从soup附加到jotain;

jotain.append(sposti.text)

只需调用print(jotain)，它将返回您需要的内容。

编辑：如果您有多个匹配标签，您可能还想使用soup.findall，否则它只会返回第一个找到的值。

Answer 3

您已将标签附加到列表中，并尝试从该列表中获取文本。这就是引发错误的原因。试试这个。

jotain.append(sposti.text)
print(jotain)

您也可以尝试列表理解。

jotain.append(sposti)
jotain = [i.text for i in jotain]
print(jotain)

希望这可以使您更清楚！干杯！
