data_list = html_data['data']['list']

for i in data_list:

dit = {}

dit['股票代码'] = i['symbol']

dit['股票名字'] = i['name']

dit['当前价'] = i['current']

dit['涨跌额'] = i['chg']

dit['涨跌幅/%'] = i['percent']

dit['年初至今/%'] = i['current_year_percent']

dit['成交量'] = i['volume']

dit['成交额'] = i['amount']

dit['换手率/%'] = 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)

保存数据

import csv

f = open('股票数据.csv', mode='a', encoding='utf-8-sig', newline='')

csv_writer = csv.DictWriter(f, fieldnames=['股票代码', '股票名字', '当前价', '涨跌额', '涨跌幅/%', '年初至今/%', '成交量', '成交额', '换手率/%', '市盈率TTM', '股息率/%', '市值'])

csv_writer.writeheader()

csv_writer.writerow(dit)

f.close()
