闲着没事写了个代码,爬取彩票数据,以生成Excel表格但如何将其进行图表分析呢,求大神讲解一下
- import requests
- import xlwt
- import time
- from bs4 import BeautifulSoup
- # 获取网页内容
- def get_html(url):
- headers = {
- 'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36'
- }
- response = requests.get(url, headers = headers)
- if response.status_code == 200:
- return response.text
- else:
- print('无数据!')
- return None
- # 解析网页内容
- def parse_html(html):
- soup = BeautifulSoup(html, 'lxml')
- i = 0
- for item in soup.select('tr')[2:-1]:
- yield{
- 'time':item.select('td')[i].text,
- 'issue':item.select('td')[i+1].text,
- 'digits':item.select('td em')[0].text,
- 'ten_digits':item.select('td em')[1].text,
- 'hundred_digits':item.select('td em')[2].text,
- 'single_selection':item.select('td')[i+3].text,
- 'three_selection':item.select('td')[i+4].text,
- 'six_selection':item.select('td')[i+5].text,
- 'sales':item.select('td')[i+6].text,
- 'return_rates':item.select('td')[i+7].text
- }
- # 将数据写入excel表
- def write_to_excel():
- f = xlwt.Workbook()
- sheet1 = f.add_sheet('3D', cell_overwrite_ok=True)
- row0 = ['开奖日期','期号','个位数','十位数','百位数','单数','组选3','组选6','销售额','反奖比列']
- # 写入第一行
- for j in range(0, len(row0)):
- sheet1.write(0, j, row0[j])
- # 依次爬取每一个网页,将结果写入excel
- i = 0
- for k in range(1, 276): #更改数字调节期数
- url = 'http://kaijiang.zhcw.com/zhcw/html/3d/list_{}.html'.format(k)
- html = get_html(url)
- print('正在保存第{}页......'.format(k))
- if html != None:
- # 写入每一期信息
- for item in parse_html(html):
- sheet1.write(i+1, 0, item['time'])
- sheet1.write(i+1, 1, item['issue'])
- sheet1.write(i+1, 2, item['digits'])
- sheet1.write(i+1, 3, item['ten_digits'])
- sheet1.write(i+1, 4, item['hundred_digits'])
- sheet1.write(i+1, 5, item['single_selection'])
- sheet1.write(i+1, 6, item['three_selection'])
- sheet1.write(i+1, 7, item['six_selection'])
- sheet1.write(i+1, 8, item['sales'])
- sheet1.write(i+1, 9, item['return_rates'])
- i += 1
- f.save('3D.xls')
- def main():
- write_to_excel()
- if __name__ == '__main__':
- main()
