Python中复杂数据结构的嵌套应用
列表嵌套字典结构
result = []
for element in elements_list:
item_dict = {}
titles.append(element.string)
urls.append(element.get('href'))
item_dict['标题'] = element.string
item_dict['完整链接'] = base_url + element.get('href')
result.append(item_dict)
列表嵌套元组结构（从字典转换而来）
for element in elements_list:
titles.append(element.string)
urls.append(element.get('href'))
mapping[element.string] = base_url + element.get('href')
print(list(mapping.items()))
tuple_list = list(mapping.items())
zipped_data = list(zip(mapping.keys(), mapping.values()))
print(list(zip(mapping.keys(), mapping.values())))
print(zipped_data[0][0])
print(tuple_list[0][0])
字典嵌套列表结构
collection_dict = {
'编号': [],
'标题': [],
'链接': [],
'作者': []
}
for index in range(len(titles)):
collection_dict["编号"].append(index)
collection_dict["标题"].append(titles[index].string)
collection_dict["链接"].append(base_url + titles[index].a.get('href'))
collection_dict["作者"].append(authors[index].text)
{'编号': [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29], '标题': ['封神开始：化身荒天帝，杀进灵山', '全民机战,火力不足恐惧症治好了', '海洋传奇：我有一颗自然之心', '我有神级修炼石', '长得太凶，被校花请去鬼宅镇邪', '塔防求生：超神附魔师', '封神：带着杨戬入阐教，一键满级', '玄幻：开局创建镇魔司', '满级灵压的我，成了鬼楼楼长！', '灵气复苏：亿万细胞同时修炼', '别人驭鬼我育鬼', '直播：这个侦探逆天了', '邪恶天敌系统，开局擒获大毒枭', '绑定国运：开局扮演人间武圣！', '超级教师：学生努力，我变强！', '惊悚游戏：百岁的我无敌于世', '国运武侠：扮演剑圣，队友邀月', '深海求生：开局一艘潜水艇', '全民驭鬼：开局厉鬼复苏', '重生：与青梅竹马一起奋斗的温馨日常', '末世：我的世界变异了', '全民塔防：我有无限合成栏', '一首大鱼，惊艳了世界！', '终极战神，金时空签到十八年', '大明：我在锦衣卫上班', '全球魔王，开局自带万界怪物模板', '武林金榜现世，我被邀月偷听心声', '特工：开局收了顾耀东为徒！', '大唐：我的穿越生活', '全民机战：火力不足恐惧症治好了'], '链接': ['https://b.faloo.com/992683.html', 'https://b.faloo.com/1004814.html', 'https://b.faloo.com/1005095.html', 'https://b.faloo.com/623185.html', 'https://b.faloo.com/1006393.html', 'https://b.faloo.com/1006390.html', 'https://b.faloo.com/997514.html', 'https://b.faloo.com/1005909.html', 'https://b.faloo.com/1007308.html', 'https://b.faloo.com/681624.html', 'https://b.faloo.com/1004071.html', 'https://b.faloo.com/1007010.html', 'https://b.faloo.com/1009516.html', 'https://b.faloo.com/1001856.html', 'https://b.faloo.com/1006127.html', 'https://b.faloo.com/1005335.html', 'https://b.faloo.com/1004661.html', 'https://b.faloo.com/1008608.html', 'https://b.faloo.com/1004429.html', 'https://b.faloo.com/843448.html', 'https://b.faloo.com/628786.html', 'https://b.faloo.com/983823.html', 'https://b.faloo.com/990011.html', 'https://b.faloo.com/860339.html', 'https://b.faloo.com/792704.html', 'https://b.faloo.com/984141.html', 'https://b.faloo.com/975276.html', 'https://b.faloo.com/858342.html', 'https://b.faloo.com/578410.html', 'https://b.faloo.com/996995.html'], '作者': ['飞飞公主', '小飞飞呀', '丁飞飞', '肥龙飞飞飞', '秦唐飞飞', '鱼飞飞', '飞飞公主', '鱼飞飞', '鱼飞飞', '飞飞费', '鱼飞飞', '公子飞飞', '公子飞飞', '鱼飞飞', '鱼飞飞', '鱼飞飞', '秦唐飞飞', '鱼飞飞', '鱼飞飞', '叶飞飞', '我要飞飞嚓嚓', '鱼飞飞', '娱乐飞飞', '飞飞啊1', '飞飞飞猫', '小飞飞呀', '秦唐飞飞', '龙飞飞', '七月飞飞', '小飞飞呀']}
