用python爬取基金网信息数据,保存到表格,并做成四种简单可视化。(爬虫之路,永无止境!)

上次 2021-07-07写的用python爬取腾讯招聘网岗位信息保存到表格,并做成简单可视化。
有的人留言问我:
可以作为模板么?
我的回答:
可以,可以拿做模板使用
今天我带大家再来使用一下这个模板
开发环境
windows10
python3.6
开发工具
pycharm

matplotlib、numpy、lxml

代码展示:

在这里插入图片描述

爬虫代码还是很简单的

1.start_url = ‘http://fund.eastmoney.com/fund.html’
2.使用ua大列表,进行ua的替换
3.获取页面源码,然后解析
4.进行xpath语法提取相应的数据
在这里插入图片描述

    def __init__(self):
        # 起始的请求地址----初始化
        self.start_url = 'http://fund.eastmoney.com/fund.html'

    def parse_start_url(self):
        """
        发送请求,获取响应

        # 请求头

            # 通过随机模块提供的随机拿取数据方法
            'User-Agent': random.choice(USER_AGENT_LIST)
        }
        # 发送请求,获取响应字节数据
        response = session.get(self.start_url, headers=headers).content
        """序列化对象,将字节内容数据,经过转换,变成可进行xpath操作的对象"""
        response = etree.HTML(response)
        """调用提取第二份响应数据"""
        self.parse_response_data(response)


    def parse_response_data(self, response):
        """
        解析response响应数据,提取

        # 股票名称
        name_list_1 = response.xpath('//tbody/tr/td[5]/nobr/a[1]/text()')

        # 昨日单位净值
        num_1_list_data_1 = response.xpath('//tbody/tr/td[6]/text()')

        # 昨日累计净值
        num_2_list_data_1 = response.xpath('//tbody/tr/td[7]/text()')

将数据保存到表格,先将数据遍历

 # 遍历解析3个列表数据
        for a, b, c in zip(name_list, num_1_list, num_2_list):
            # 构造保存的excel字典数据
            dict_data = {
                # 会根据该字典的key值创建工作簿的sheet名
                '股票数据': [a, b, c]
            }
            """调用解析保存excel表格方法"""
            self.parse_save_excel(dict_data)

生成四种简单可视化

            # 昨日累计净值列表
            qy_num_2.append(num_2_list[index_num])

生成折线图

plt.rcParams['font.sans-serif'] = ['SimHei']
        plt.rcParams['axes.unicode_minus'] = False
        # plot中参数的含义分别是横轴值,纵轴值,线的形状,颜色,透明度,线的宽度和标签
