how does requests-html get the innerText of a tag

def stage_catch():
    session = HTMLSession()
    r = session.get("http://www.dmzx.com/manhua/358/")
    div = r.html.find(".subsrbelist")
    list_a = div[0].find("ul")[0].find("a")     -sharp 
    for a in list_a:

        print(a)
        print(a.attrs)
        print(a.text)

        -sharp pages = re.sub("\D", "", total_pages)
        -sharp print(pages)
    pass
if __name__ == "__main__":
    stage_catch()

this is my corresponding node

<a href="http://www.dmzx.com/manhua/358/2000089062.html" title="360" target="_blank">
    <span class="red">360</span> 
        (18)
</a>

<Element "a" href="http://www.dmzx.com/manhua/358/2000089062.html" title="360" target="_blank">
{"href": "http://www.dmzx.com/manhua/358/2000089062.html", "title": "360", "target": "_blank"}
 (360) (18)

these are my three outputs. When I use a.text to output, I am not

I want to call something like a.innerText to get innerText directly, that is, "(18 pages)", but there is no such method.

I temporarily converted to a string and then processed the corresponding string.

I want to know what I can do to test the corresponding methods in js for these python libraries.

I tried dir (a) to get the method, and everything related to text tried once on the page and found that it didn"t work.
