Python爬取股票資訊，並實現可視化數據

前言

截止2019年年底中國股票投資者數量為15975.24萬戶, 如此多的股民熱衷於炒股,首先拋開炒股技術不說, 那麼多股票數據是不是非常難找, 找到之後是不是看著密密麻麻的數據是不是頭都大了?

今天帶大家爬取雪球平台的股票數據, 並且實現數據可視化

先看下效果圖

 

基本環境配置

  • python 3.6
  • pycharm
  • requests
  • csv
  • time

目標地址

//xueqiu.com/hq

 

 

爬蟲程式碼

請求網頁

import requests
url = '//xueqiu.com/service/v5/stock/screener/quote/list'
response = requests.get(url=url, params=params, headers=headers, cookies=cookies)
html_data = response.json()
#想要完整程式碼的同學請關注微信公眾號：松鼠愛吃餅乾
#發送資訊『股票』即可獲取

 

解析數據

data_list = html_data['data']['list']
for i in data_list:
    dit = {}
    dit['股票程式碼'] = i['symbol']
    dit['股票名字'] = i['name']
    dit['當前價'] = i['current']
    dit['漲跌額'] = i['chg']
    dit['漲跌幅/%'] = i['percent']
    dit['年初至今/%'] = i['current_year_percent']
    dit['成交量'] = i['volume']
    dit['成交額'] = i['amount']
    dit['換手率/%'] = i['turnover_rate']
    dit['市盈率TTM'] = i['pe_ttm']
    dit['股息率/%'] = i['dividend_yield']
    dit['市值'] = i['market_capital']
    print(dit)

 

保存數據

import csv
f = open('股票數據.csv', mode='a', encoding='utf-8-sig', newline='')
csv_writer = csv.DictWriter(f, fieldnames=['股票程式碼', '股票名字', '當前價', '漲跌額', '漲跌幅/%', '年初至今/%', '成交量', '成交額', '換手率/%', '市盈率TTM', '股息率/%', '市值'])
csv_writer.writeheader()
csv_writer.writerow(dit)
f.close()

 

 

 

數據分析程式碼

c = (
    Bar()
        .add_xaxis(list(df2['股票名稱'].values))
        .add_yaxis("股票成交量情況", list(df2['成交量'].values))
        .set_global_opts(
        title_opts=opts.TitleOpts(title="成交量圖表 - Volume chart"),
        datazoom_opts=opts.DataZoomOpts(),
    )
        .render("data.html")
)
