为什么当我尝试使用 find_all 函数在 Python 3.8 中使用 bs4 通过带有“class_”的 css 进行搜索时得到一个空列表？

Question

I wanna get all links which includes specific class. Therefore i am using this code:

def getProductList(data, pageLinks):
    content = BeautifulSoup(data.content, 'html.parser')
    a = content.find_all("a", class_="sresult lvresult clearfix li shic")
    print(a)

but im getting this output and i know that there are lots of links includes this class:

C:/Users/projects/getData.py
    []

I checked the doc and it should be true. What is wrong with this code?

Answer 1

根据链接的文档，它应该是 class_= 而不是 class_：
