不能同时从网页中抓取两个字段

Question

我正试图把series name和product code一起从网页中刮走。我创建的脚本可以完美地获取product code，但我不知道如何获取系列名称和产品代码。

我已经试过了：

import requests
from bs4 import BeautifulSoup

link = 'https://www.theimagingsource.com/products/industrial-cameras/usb-3.1-monochrome/'

with requests.Session() as s:
    s.headers['User-Agent'] = 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.150 Safari/537.36'
    res = s.get(link)
    soup = BeautifulSoup(res.text,"lxml")
    for item in soup.select("td.product-code > a[title]"):
        print(item.get_text(strip=True))

我得到的输出：

DMK 38UX267
DMK 38UX255
DMK 38UX304
DMK 38UX253
DMK 37AUX287
DMK 37AUX273
DMK 37AUX290

我希望得到的产出：

38 series - USB 3.1 monochrome industrial cameras DMK 38UX267
38 series - USB 3.1 monochrome industrial cameras DMK 38UX255
38 series - USB 3.1 monochrome industrial cameras DMK 38UX304
38 series - USB 3.1 monochrome industrial cameras DMK 38UX253
37 A series - USB 3.1 monochrome industrial cameras DMK 37AUX287
37 A series - USB 3.1 monochrome industrial cameras DMK 37AUX273
37 A series - USB 3.1 monochrome industrial cameras DMK 37AUX290

等等

使用.find_previous('h3')

import requests
from bs4 import BeautifulSoup

link = "https://www.theimagingsource.com/products/industrial-cameras/usb-3.1-monochrome/"

with requests.Session() as s:
    s.headers[
        "User-Agent"
    ] = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.150 Safari/537.36"
    res = s.get(link)
    soup = BeautifulSoup(res.text, "lxml")
    for item in soup.select("td.product-code > a[title]"):
        print(
            item.find_previous("h3").get_text(strip=True),
            item.get_text(strip=True),
        )
