from bs4 import BeautifulSoup

import win_unicode_console
win_unicode_console.enable()
link = ('https://pietroalbini.io/')
req = urllib.request.Request(link, headers={'User-Agent': 'Mozilla/5.0'})
url = urllib.request.urlopen(req).read()
soup = BeautifulSoup(url, "html.parser")
body = soup.find_all('div', {"class":"wrapper"})
print(body.text)
Hi, I have a problem with Beautiful Soup, if I run this code without ".text" at the end it show me a list of div but if I add ".text" at the end come the error
嗨，我有一个关于 Beautiful Soup 的问题，如果我在最后没有“.text”的情况下运行这段代码，它会显示一个 div 列表，但如果我在最后添加“.text”就会出现错误

find_allreturns a ResultSet object which you can iterate over using a forloop. What you can do is:
find_all返回一个 ResultSet 对象，您可以使用for循环对其进行迭代。你可以做的是：
for wrapper in body.find_all('div', {"class":"wrapper"}):
print wrapper.text

If you'll type:
如果你输入：
print(type(body))
you'll see bodyis <class 'bs4.element.ResultSet'>It means allthe elements that match the class. You can either iterate over them:
你会看到bodyis<class 'bs4.element.ResultSet'>表示与类匹配的所有元素。您可以遍历它们：
for div in body:
print(div.text)
Or if you know you only have div, you can use findinstead:
或者，如果您知道您只有 div，则可以使用find：
div = soup.find('div', {"class":"wrapper"})
div.text

Probably should have posted as answer.. so as stated in the comments almost verbatim
可能应该作为答案发布......所以正如评论中几乎逐字所述
Your code should be the following:
您的代码应如下所示：
for div in body:
print div.text
#python3
#print(div.text)
Or some naming schema to your preference thereof.
或者一些你喜欢的命名模式。
The find_allmethod returns a generated list ( loosely using the term list here ) of items that beautifulsoup has found matching your criteria after parsing the source webpages html either recursively or non-recursively depending upon how you search.
该find_all方法返回一个生成的列表（在这里松散地使用术语列表），在根据您的搜索方式递归或非递归地解析源网页 html 后，beautifulsoup 发现匹配您的条件的项目。
As the error says the resulting set of objects has no attribute text, since it isn't an element but rather a collection of them. However, the items inside the resulting set ( should any be found ) do.
正如错误所说，结果对象集没有属性文本，因为它不是元素而是它们的集合。但是，结果集内的项目（应该有任何发现）可以。
