python中如何提取JSON格式花括号中的jpg

怎样才能拿到jpg呀，这种数据类型不会提取（thumbnail': 'https://b2c.azz.net/s6/image/2022/10/17/254bc1b077.jpg'）
下面那个代码是我写了一点了，接下来搞不出来了，求指导

import json
import requests

url = 'https://wlop.huotan.com/api/v2/product/list/5?category=FKi70&page=1'
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/106.0.0.0 Safari/537.36'
}

resp = requests.get(url, headers=headers)
data = resp.json()
lists = data['data']['list']
print(lists)

import json
import requests
from urllib.request import urlretrieve
url = 'https://wlop.huotan.com/api/v2/product/list/5?category=FKi70&page=1'
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/106.0.0.0 Safari/537.36'
}
resp = requests.get(url, headers=headers)
data = resp.json()
lists = data['data']['list']
##获取里面的图片
for item in lists:
    pic_url = item.get('thumbnail')
    print(pic_url)
    pic_name = pic_url.rsplit('/',1)[1]
    # urlretrieve(pic_url,pic_name)      # 下载图片
