问题是导出到CSV文件，当我打开“ prod.csv”文件时，它似乎只包括所抓取信息的最后一页（25个项目），没有标题。每个要抓取的页面包含25个项目，共5个页面（总共125个产品）应该在我的csv文件中。只是想知道如何包含所有带有标题的数据。谢谢！

Answer 1

问题在于您正在用新数据覆盖密钥，因此可以改为使用namedtuple()。

import collections

all_products = collections.namedtuple('Products', ['Name', 'Brand', 'Packaging', 'Availability', 'Price'])

Answer 2

每次all_product将设置为[]，因此all_product仅包含最后一页的结果。您必须在循环外部定义all_product。

all_product = []

for i in range(1, 5):
    #code
