Chinese Lottery Predict

Analyzes historical data from major Chinese lottery websites to provide statistical predictions for the next draw.

Prerequisites

• WebSearch: To fetch the latest lottery results.
• Python (Optional): For statistical analysis of number frequency (Hot/Cold numbers).

Workflow

1. Input Parsing

The user will provide:

• Lottery Type: e.g., "双色球" (Double Color Ball) or "大乐透" (Super Lotto).
• Funds (Optional): Budget for the purchase (default: "10元").

2. Data Retrieval Strategy

采用四级数据获取策略，确保数据准确性和可靠性：

第一级：直接数据抓取（首选）

1. 多数据源并行获取：

   • 中彩网 (zhcw.com) - 官方权威数据
   • 500彩票网 (500.com) - 行业领先平台
   • 新浪彩票 (sina.com.cn) - 门户网站数据

2. 数据验证机制：

   • 每个数据源必须返回完整的号码集合（红球33个，蓝球16个）
   • 至少需要2个数据源验证通过
   • 数据不一致时采用多数原则

第二级：搜索引擎抓取（备用）

1. 当直接抓取失败时，使用搜索引擎获取数据
2. 搜索策略：
   • 使用 DuckDuckGo、Bing、百度等多引擎搜索
   • 关键词："{彩票类型}" 最新开奖结果、"{彩票类型}" 历史号码
   • 从搜索结果页面提取结构化数据

第三级：WebSearch工具（如有配置）

1. 如果配置了WebSearch API密钥，使用官方搜索工具
2. 搜索关键词：
   • "{彩票类型}" 近50期开奖结果
   • site:zhcw.com {彩票类型} 往期

第四级：静态数据分析（兜底）

1. 使用内置的历史数据样本
2. 基于统计学原理生成建议
3. 明确标注数据来源为"模拟数据"

数据质量保障

1. 交叉验证：至少2个独立数据源验证
2. 完整性检查：必须包含所有可能号码
3. 时效性检查：数据应包含近期开奖结果
4. 一致性检查：热号/冷号趋势应基本一致

3. Data Analysis

Analyze the retrieved data to identify:

• Hot Numbers: Numbers that appeared most frequently in the last 30 draws.
• Cold Numbers: Numbers that haven't appeared in a long time.
• Omitted Numbers: Current omission count for each number.

4. Prediction Generation

Generate 1-5 sets of numbers based on a mix of Hot and Cold numbers. Disclaimer: Lottery draws are independent random events. Predictions are for entertainment only.

5. Output Generation

Generate a report in Chinese using the following format.

Implementation Examples

Python Implementation for Data Retrieval

import requests
import re
from collections import Counter

def fetch_lottery_data(lottery_type="双色球"):
    '''从多个数据源获取彩票数据'''
    data_sources = [
        {'name': '中彩网', 'url': 'https://www.zhcw.com/ssq/'},
        {'name': '500彩票网', 'url': 'https://kaijiang.500.com/ssq.shtml'},
    ]
    
    all_reds = []
    all_blues = []
    
    for source in data_sources:
        try:
            response = requests.get(source['url'], headers={'User-Agent': 'Mozilla/5.0'}, timeout=15)
            if response.status_code == 200:
                numbers = re.findall(r'(\\d{2})', response.text)
                reds = [n for n in numbers if n.isdigit() and 1 <= int(n) <= 33]
                blues = [n for n in numbers if n.isdigit() and 1 <= int(n) <= 16]
                
                if len(set(reds)) >= 30 and len(set(blues)) >= 14:
                    all_reds.extend(reds)
                    all_blues.extend(blues)
        except:
            continue
    
    return all_reds, all_blues

def analyze_numbers(reds, blues):
    '''分析热号和冷号'''
    red_counter = Counter(reds)
    blue_counter = Counter(blues)
    
    hot_reds = [num for num, _ in red_counter.most_common(10)]
    hot_blues = [num for num, _ in blue_counter.most_common(5)]
    cold_reds = [num for num, _ in red_counter.most_common()[-10:]]
    cold_blues = [num for num, _ in blue_counter.most_common()[-5:]]
    
    return {
        'hot_reds': hot_reds,
        'hot_blues': hot_blues,

DuckDuckGo Search Implementation

import requests
from bs4 import BeautifulSoup

def duckduckgo_search(query, max_results=5):
    '''使用DuckDuckGo进行搜索'''
    url = 'https://html.duckduckgo.com/html/'
    params = {'q': query, 'kl': 'us-en', 'kp': '1'}
    
    response = requests.get(url, params=params, headers={'User-Agent': 'Mozilla/5.0'}, timeout=15)
    if response.status_code == 200:
        soup = BeautifulSoup(response.text, 'html.parser')
        results = []
        
        for result in soup.find_all('div', class_='result')[:max_results]:
            title_elem = result.find('a', class_='result__title')
            link_elem = result.find('a', class_='result__url')
            snippet_elem = result.find('a', class_='result__snippet')
            
            if title_elem and link_elem:
                results.append({
                    'title': title_elem.get_text(strip=True)
