国外价值10K+美金的Python面试题，珍藏已久，含泪放了出来

兄弟们，没吹牛皮，一哥们在国外面试的时候，就是要他做的这个，直接给他说，做出来了给你15K（单位是刀），做不出来就拜拜~

大兄弟当时就不服了，这不是看不起我么，分分钟就给整完了~

我上我也行系列：

唠唠叨叨一下 （https://jq.qq.com/?_wv=1027&k=UEbz4NcQ）

那我们直接开整，像我们练手的话，装好Python和pycharm就OK了，没安装的话先安装好，这里我就不写了。

1、主要知识点

爬虫基本流程
非结构化数据解析
表格类型数据保存

2、第三方库安装的几种方法 （https://jq.qq.com/?_wv=1027&k=UEbz4NcQ）

requests
parsel 

直接pip安装即可

1)、cmd中使用pip命令安装

win+r打开搜索出入cmd 按回车确认

然后在弹出来的命令提示符窗口输入pip安装指令加上模块，比如安装requests , 输入 pip install requests 按回车即可 。

2)、在pycharm设置里安装 （https://jq.qq.com/?_wv=1027&k=UEbz4NcQ）

3)、在pycharm使用pip命令安装

输入 pip install requests 按回车即可

代码部分 （https://jq.qq.com/?_wv=1027&k=UEbz4NcQ）

1、代码实现流程

发送请求(访问网站)
获取数据(网页源代码)
解析数据(提取我们想要的数据内容 详情页链接)
发送请求(访问所有的详情页链接) 获取数据
解析数据(提取到我们想要的数据内容)
保存数据

2、代码展示

导入模块

import requests
import parsel
import re
import csv

伪装

发送请求(访问网站)

response = requests.get(url, headers=headers)

获取数据(网页源代码)

html_data = response.text

解析数据(提取我们想要的数据内容 详情页链接)

selector = parsel.Selector(html_data)

提取标签的属性内容 ::attr(href) 链接

link_list = selector.css('.bHGqj.Cj.b::attr(href)').getall()
for link in link_list:
    link = 'tripadvisor/' + link

发送请求(访问所有的详情页链接) 获取数据

detail_html = requests.get(link, headers=headers).text

解析数据

detail_selector = parsel.Selector(detail_html)
store_name = detail_selector.css('.fHibz::text').get()
comment_count = detail_selector.css('.eSAOV.H3:nth-child(2) .eBTWs::text').get()
address = detail_selector.css('.eSAOV.H3:nth-child(3) .dyeJW.dUpPX:nth-child(1) .fhGHT::text').get()
city = detail_selector.css('.breadcrumbs li:nth-child(4) span::text').get()
phone = detail_selector.css('.eSAOV.H3:nth-child(3) .dyeJW.dUpPX:nth-child(2) .fhGHT a::text').get()
score = detail_selector.css('.eEwDq .fdsdx::text').get()
website = re.findall(',"website":"(http.*?)"', detail_html)[0]
print(store_name, comment_count, city, address, phone, score, link, website)

保存数据

with open('tripadvisor.csv', mode='a', newline='', encoding='utf-8') as f:
    csv_writer = csv.writer(f)
    csv_writer.writerow([store_name, comment_count, city, address, phone, score, link, website])

翻页

for page in range(0, 131, 30):
    print(f'-------------------正在爬取第{page+1}页-------------------')
    url = f'tripadvisor/RestaurantSearch?Action=PAGE&ajax=1&availSearchEnabled=true&sortOrder=popularity&geo=188590&itags=10591&eaterydate=2022_03_11&date=2022-03-12&time=20%3A00%3A00&people=2&o=a{page}'

兄弟们，帮我动动小手，点个赞+收藏，还可以顺便评论一下，下次给大家弄个Python 30k 岗位的面试题补充一下点赞花掉的体力，嘿嘿~
