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-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 requestsimport osfrom bs4 import BeautifulSoupdef download(url, page):html = requests.get(url).textsoup = 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 = "/ssq.shtml"html = requests.get(url).textsoup = 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.stringdownload(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 pdimport numpy as npfrom 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 pdimport numpy as npfrom 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。
