如何使用python撰寫爬蟲程式-自動取得當日即時股價

作者

1. 安裝Requests和BeautifulSoup及lxml

pip install beautifulsoup4
pip install requests
pip install lxml

2. 撰寫程式碼：
=====以下是程式碼內容=====

 

 $ cat yahoostock.py

 

#!/usr/local/bin/python3
# -*- coding: utf-8 -*-
import sys
import requests,datetime
from bs4 import BeautifulSoup
now = datetime.datetime.now()
today = now.strftime('%Y%m%d')
stock_ids = open("stocklist.txt").read().splitlines()
for stock_id in stock_ids:
 url = 'https://tw.stock.yahoo.com/q/q?s='+stock_id
 try:
  page = requests.get(url)
  soup = BeautifulSoup(page.content, 'html.parser')
  table = soup.find_all(text='成交')[0].parent.parent.parent
  stock_name = table.select('tr')[1].select('td')[0].text
  stock_price = table.select('tr')[1].select('td')[2].text
  stock_name2 = stock_name.strip('加到投資組合')
  slist = [today,stock_id,stock_price,stock_name2]
  print('|'.join(slist))  #OUTPUT FORMATE: 20200314|0050|81.00
 except:
  print('錯誤或無此代碼!!')

在Linux或是macOS底下，為了方便使用，第一行直接宣告環境變數，讓python程式可以和shell script有一樣的執行方式

3. 關注的股票代碼：
=====以下是檔名及內容格式=====

$ cat stocklist.txt
0050
0056
00679B
2330

4. 執行結果如下：

$ ./yahoostock.py
20200314|0050|81.00|0050元大台灣50
20200314|0056|25.29|0056元大高股息
20200314|00679B|48.47|00679B元大美債20年
20200314|2330|290.0|2330台積電

  5. I’m the co-founder of JustCBD Store brand (justcbdstore.com) and I am currently aiming to develop my wholesale side of company. I really hope that anybody at targetdomain can help me . I considered that the most effective way to accomplish this would be to talk to vape companies and cbd stores. I was really hoping if anyone could recommend a trustworthy site where I can buy CBD Shops B2B Database I am currently taking a look at creativebeartech.com, theeliquidboutique.co.uk and wowitloveithaveit.com. On the fence which one would be the best selection and would appreciate any advice on this. Or would it be easier for me to scrape my own leads? Suggestions?
