前言

嗨喽~大家好呀，这里是魔王呐 ❤ ~!

Python采集双色球历史开奖信息，看看哪个号中奖概率更大,python爬虫,python,开发语言,pycharm

知识点:

爬虫基本流程
requests的使用
动态数据抓包

开发环境:

解释器: python 3.8
编辑器: pycharm 2022.3
requests >>> pip install requests

第三方模块安装:

win + R 输入cmd 输入安装命令 pip install 模块名 (如果你觉得安装速度比较慢, 你可以切换国内镜像源)

python资料、源码、教程\福利皆: 点击此处跳转文末名片获取

基本流程:

一. 思路分析

找到数据来源

    当前的这个数据 是动态数据还是静态数据
    
    network 网络资源抓包  
    
捋清楚整个案例的实现过程

    访问该网址 获取到 数据内容
    
    并且将我们需要的数据内容提取出来
    
    保存 (单页)
    
    多页采集 分析 链接变化规律 构建翻页规律 实现多页采集

二. 代码实现

发送请求
获取数据
解析数据
保存数据
