使用beautifulsoup从“td”标签解析整数

我读了很多关于beautifulsoup的文章，但我还是不明白。我需要一个例子。

我想获得“PD/DD”的值，即 1,9。

这是来源：

<div class="table vertical">
    <table>
        <tbody>
            <tr>
                <th>F/K</th>
                <td>A/D</td>
            </tr>
            <tr>
                <th>FD/FAVÖK</th>
                <td>19,7</td>
            </tr>
            <tr>
    HERE-->    <th>PD/DD</th> 
    HERE-->    <td>1,9</td> 
            </tr>
            <tr>
                <th>FD/Satışlar</th>
                <td>5,1</td>
            </tr>
            <tr>
                <th>Yabancı Oranı (%)</th>
                <td>2,43</td>
            </tr>
            <tr>
                <th>Ort Hacim (mn$) 3A/12A</th>
                <td>1,3 / 1,6</td>
            </tr>

我的代码是：

a="afyon"

url_bank = "https://www.isyatirim.com.tr/tr-tr/analiz/hisse/sayfalar/sirket-karti.aspx?hisse={}".format(a.upper())

response_bank = requests.get(url_bank)
html_content_bank = response_bank.content
soup_bank = BeautifulSoup(html_content_bank, "html.parser")
b=soup_bank.find_all("div", {"class": "table vertical"})

for i in b:
    children = i.findChildren("td" , recursive=True)


    for child in children:
        l=[]
        l_text = child.text
        l.append(l_text)
        print(l)

当我运行这段代码时，它给了我一个带有 1 个索引的列表。

['Afyon Çimento                 ']
['11.04.1990']
['Çimento üretip satmak ve ana faaliyet konusu ile ilgili her türlü yan sanayi kuruluşlarına iştirak etmek.']
['(0216)5547000']
['(0216)6511415']
['Kısıklı Cad. Sarkusyan-Ak İş Merkezi S Blok kat:2 34662 Altunizade - Üsküdar / İstanbul']
['A/D']
['19,7']
['1,9']
['5,1']
['2,43']
['1,3 / 1,6']
['407,0 mnTL']
['395,0 mnTL']
['-']

我怎样才能只获得 PD/DD 值。我期待这样的事情：

PD/DD : 1,9
