本文主要是介绍python爬虫股票数据分析判断股票好坏_Python爬取股票信息，并可视化数据的示例...，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

前言

截止2019年年底我国股票投资者数量为15975.24万户, 如此多的股民热衷于炒股,首先抛开炒股技术不说, 那么多股票数据是不是非常难找, 找到之后是不是看着密密麻麻的数据是不是头都大了?

今天带大家爬取雪球平台的股票数据, 并且实现数据可视化

先看下效果图

基本环境配置

python 3.6

pycharm

requests

csv

time

目标地址

爬虫代码

请求网页

import requests

url = 'https://xueqiu.com/service/v5/stock/screener/quote/list'

response = requests.get(url=url, params=params, headers=headers, cookies=cookies)

html_data = response.json()

解析数据

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()

完整代码

import pprint

import requests

import time

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', '股票名称', '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'])
