同花顺问财数据获取方法
同花顺问财是金融数据获取的重要工具，提供股票、基金、宏观经济等各类金融数据。通过Python可以高效地从问财获取所需数据。
安装必要库
使用requests和pandas库处理网络请求和数据整理：
pip install requests pandas基本数据获取代码框架
构建获取问财数据的通用代码框架：
import requests import pandas as pd def get_wencai_data(query, columns=None): url = f"http://www.iwencai.com/unifiedwap/unified-wap/result/get-stock-pick" params = { "question": query, "perpage": 10000 } headers = { "User-Agent": "Mozilla/5.0" } response = requests.get(url, params=params, headers=headers) data = response.json()["data"]["list"] df = pd.DataFrame(data) if columns: df = df[columns] return df常用查询示例
获取A股所有股票代码和名称：
stock_list = get_wencai_data("A股股票", columns=["股票代码", "股票简称"])筛选市盈率低于10倍的股票：
low_pe_stocks = get_wencai_data("市盈率小于10 主板", columns=["股票代码", "股票简称", "市盈率"])数据清洗与处理
对获取的数据进行清洗和处理：
# 转换数值型数据 low_pe_stocks["市盈率"] = pd.to_numeric(low_pe_stocks["市盈率"], errors="coerce") # 去除异常值 clean_data = low_pe_stocks.dropna()https://www.zhihu.com/zvideo/1994547787254227729/

高级查询技巧
使用问财的高级语法进行复杂查询：
# 查询ROE连续3年大于15%的股票 quality_stocks = get_wencai_data("ROE连续3年大于15% 非ST", columns=["股票代码", "股票简称", "ROE"])注意事项
问财数据接口可能有访问频率限制，建议合理控制请求频率。对于大量数据获取，考虑分批次查询。商业用途需遵守同花顺的相关使用条款。
