response = requests.get(url=url, headers=headers)
json = response.json()
data1 = json['data']['list']
for list in data1:
print(list) 可以把url里面的page参数通过循环来填充，这样就可以实现翻页了。还可以试试size调大一些有没有用，能不能加大一下每页返回的数量。如果size大一些，发送翻页请求的次数就会少一些，可以加快爬取速度。之余保存数据到文件里面，你引入的那个 csv 模块就可以做这个，具体查一下 csv 模块怎么使用就好
不建议使用 list 作为变量名
