从列表类型中移除所有 {}

Question

大家好，我正在抓取亚马逊网站，我正在获取所有 16 个链接，但想从新生成的列表中删除 {} 部分。提供的输出

from requests_html import HTMLSession

import time

import pandas as pd


s = HTMLSession()


r = s.get("https://www.amazon.in/s?k=oneplus&page=1")

r.html.render(sleep=1)

t= []


Everything = r.html.find("div.s-include-content-margin.s-border-bottom.s-latency-cf-section")


for e in Everything:

links = e.find("a.a-link-normal.a-text-normal")[0].absolute_links

t.append(links)

print("\n",t)

Answer 1

你基本上得到了一个集合列表。为了将 set 的每个元素转换为列表元素，请使用itertools.chain.from_iterable. 文档

from itertools import chain
l = list(chain.from_iterable(t))
