东方财富如何查股票代码（内附完整程序代码）

部分网页源码

第二步，从第一步获取的网页源码数据找到我们需要的目标数据，网页源码按照一定的格式标签排列，通过标签访问目标数据，这个过程称为数据解析和查找。目标函数

解析函数soup = BeautifulSoup ( html , 'html.parser' )

查找函数 find（） 或者find_all（）或者利用正则表达式对字符串进行匹配查找。

第三步，按照一定格式进行数据存储。可直接存储到txt文件即可。程序运行后部分结果数据如下图

部分结果数据

Python3.5 实现代码如下：

from bs4 import BeautifulSoup import traceback import re import time import requests def GetHTMLSource(url): # 得到目标网页源码 try: r=requests.get(url) r.raise_for_status () r.encoding = r.apparent_encoding return r.text except: print ( "异常" ) return "" def SetFileName(): dirname = time.strftime ( '%Y%m%d' , time.localtime ( time.time () ) ) #获取当前日期 dirname = 'sh' return dirname def getStockList(lst , stock_list_url): # 获得东方财富网上以sh6开头的股票代码 html = GetHTMLSource ( stock_list_url ) soupdata = BeautifulSoup ( html , 'html.parser' ) a = soupdata.find_all ( 'a' ) # 用find_all方法遍历所有'a'标签，并取出在'a'标签里面的’href’数据 for i in a: try: href = i.attrs[ 'href' ] lst.append ( re.findall ( r"sh6\d{5}" , href )[ 0 ] ) # 匹配sh6开头的股票 except: continue def getStockInfo(lst , stock_info_url , fpath): ndate = time.strftime ( '%Y%m%d' , time.localtime ( time.time () ) ) for stock in lst: url = stock_info_url stock '.html' # 具体单只股票的url html = GetHTMLSource ( url ) try: if html == "": continue infoDict = {} soup = BeautifulSoup ( html , 'html.parser' ) stockInfo = soup.find ( 'div' , attrs={'class': 'stock-bets'} ) if stockInfo == None: continue keyData = stockInfo.find_all ( 'dt' ) valueData = stockInfo.find_all ( 'dd' ) inp = stock "," ndate "," for i in range ( len ( keyData ) ): key = keyData[ i ].text val = valueData[ i ].text infoDict[ key ] = val inp = infoDict[ '最高' ] "," infoDict[ '换手率' ] "," infoDict[ '成交量' ] "," infoDict[ '成交额' ] "\n" with open ( fpath , 'a' , encoding='utf-8' ) as f: f.write ( inp ) except: traceback.print_exc () continue def main(): stock_name_url = 'http://quote.eastmoney.com/stocklist.html' stock_data_url = 'http://gupiao.baidu.com/stock/' output_file = './' SetFileName () '.txt' # 输出文件的文件名，路径在默认在项目文件夹下 slist = [ ] getStockList ( slist , stock_name_url ) #获取股票名称 getStockInfo ( slist , stock_data_url , output_file ) #根据股票名称获取数据，保存到output_file文件中 main ()
