好的,以下是符合您要求的 Python 代码:
```python
import requests
import numpy as np
from sklearn.ensemble import RandomForestClassifier
# 抓取最近50期双色球开奖号码
url = 'https://datachart.500.com/ssq/history/newinc/history.php?start=20001&end=21050'
response = requests.get(url)
data = response.text.split('\n')[2:-2]
latest_50 = []
for row in data:
row = row.split(',')
red_balls = [int(b) for b in row[2:8]]
blue_ball = int(row[8])
latest_50.append(red_balls + [blue_ball])
# 利用随机森林树算法分析抓取的近50期号码
X = np.array([row[:-1] for row in latest_50])
y = np.array([row[-1] for row in latest_50])
clf = RandomForestClassifier(n_estimators=100, max_depth=5)
clf.fit(X, y)
# 根据规律预测一注双色球号码
next_red_balls = clf.predict_proba([X[-1]])[0][:6].argsort()[::-1][:5] + 1
next_blue_ball = clf.predict([X[-1]])[0]
print('预测的下期双色球号码为:', next_red_balls, next_blue_ball)
```
