利用爬虫抓取双色球开奖号码，获取完整数据，简洁45行代码实现，更新时间2023-06-28

这是网上的数据，怎么将它爬取下来

它将只爬取最近30期的双色球开奖号码，并将结果写入到名为 "双色球开奖结果.csv" 的文件中。

import requests
import os
from bs4 import BeautifulSoup
def download(url, page):
    html = requests.get(url).text
    soup = BeautifulSoup(html, 'html.parser')
    list = soup.select('div.ball_box01 ul li')
    ball = []
    for li in list:
        ball.append(li.string)
    write_to_excel(page, ball)
    print(f"第{page}期开奖结果录入完成")
def write_to_excel(page, ball):
    f = open('双色球开奖结果.csv', 'a', encoding='utf_8_sig')
    f.write(f'第{page}期,{ball[0]},{ball[1]},{ball[2]},{ball[3]},{ball[4]},{ball[5]},{ball[6]}\n')
    f.close()
def turn_page():
    url = "http://kaijiang.500.com/ssq.shtml"
    html = requests.get(url).text
    soup = BeautifulSoup(html, 'html.parser')
    pageList = soup.select("div.iSelectList a")
    # 获取最近30期的页码
    recent_pages = pageList[:30]
    for p in recent_pages:
        url = p['href']
        page = p.string
        download(url, page)
def main():
    if os.path.exists('双色球开奖结果.csv'):
        os.remove('双色球开奖结果.csv')
    turn_page()
if __name__ == '__main__':
    main()

生成的表格打开验证数据正确性

非常好，下面写出神经网络进行预测

import pandas as pd
import numpy as np
from sklearn.ensemble import RandomForestRegressor
# 读取数据
data = pd.read_csv('双色球开奖结果.csv')
# 提取特征和标签
features = data.iloc[:, 1:7]  # 红色球特征
labels = data.iloc[:, 1:7]  # 红色球标签
# 创建随机森林回归模型
model = RandomForestRegressor(n_estimators=100, random_state=1)
# 拟合模型
model.fit(features, labels)
# 预测下一期的红色球号码
next_features = model.predict(features.iloc[-1].values.reshape(1, -1))
next_features = np.round(next_features).astype(int)
# 打印预测的红色球号码
print("预测的红色球号码:", next_features)

 这个预测方式好像有点简单了，弄一个多层感知机进行预测

import pandas as pd
import numpy as np
from sklearn.neural_network import MLPRegressor
# 读取数据
data = pd.read_csv('双色球开奖结果.csv')
# 提取特征和标签
features = data.iloc[:, 1:7]  # 红色球特征
labels = data.iloc[:, 1:7]  # 红色球标签
# 创建多层感知机回归模型
model = MLPRegressor(hidden_layer_sizes=(100,), random_state=1)
# 拟合模型
model.fit(features, labels)
# 预测下一期的红色球号码
next_features = model.predict(features.iloc[[-1]])
next_features = np.round(next_features).astype(int)
# 打印预测的红色球号码
print("预测的红色球号码:", next_features)

这两个代码预测的号码不一样，可能是因为使用的模型不一样导致的。随便玩玩吧。

再做一个模拟双色球游戏，如果选择的号码中了，会显示绿色。
