生成一段python代码,抓取双色球近50期开奖数据,利用beautifulsoup清洗数据,只保留开奖期号和开奖号码,存放在列表list50中,利用随机森林数算法分析list50中数据,预测下一期双色球开奖号码

以下是生成的Python代码,注意需要安装BeautifulSoup库和sklearn库:
```python
import requests
from bs4 import BeautifulSoup
from sklearn.ensemble import RandomForestRegressor
# 抓取双色球近50期开奖数据
url = 'http://kaijiang.zhcw.com/zhcw/html/ssq/list_1.html'
r = requests.get(url)
soup = BeautifulSoup(r.content, 'html.parser')
table = soup.find('table', attrs={'class': 'wqhgt'})
rows = table.find_all('tr')[2:]
list50 = []
for row in rows:
cols = row.find_all('td')
period = cols[0].text.strip()
nums = [int(col.text.strip()) for col in cols[1:7]]
list50.append((period, nums))
# 随机森林数算法分析数据
X = [[int(num) for num in period[1]] for period in list50]
y = [period[1][-1] for period in list50]
rf = RandomForestRegressor(n_estimators=100, random_state=42)
rf.fit(X, y)
# 预测下一期双色球开奖号码
new_period = '2022001' # 假设要预测的下一期期号为2022001
new_nums = rf.predict([[int(num) for num in new_period]])
print('预测的下一期双色球开奖号码为:', [int(num) for num in new_nums])
```
注意:上述程序仅供参考,因为数据的不确定性和算法的不确定性,预测结果可能会有误差。
