Python撰寫爬蟲程式

  今天心血來潮來練習一下以前學過的python,先找一個範例來練練手

以下是爬蟲程式爬台灣銀行黃金資料:

#台灣銀行黃金價格

import time

import urllib.request as request

from bs4 import BeautifulSoup as sp

import requests

local_time = time.ctime(time.time())

url="https://rate.bot.com.tw/gold?Lang=zh-TW" ###

with request.urlopen(url) as response:

  data=response.read().decode("utf-8")

  root=sp(data,"html.parser")

  gold_in=(root.find_all("td")[5].text.replace("回售","").strip()) ###

  gold_out=(root.find_all("td")[2].text.replace("買進","").strip()) ###

  s1=("\nGold"+"\n銀行買進: "+gold_in+"\n銀行賣出: "+gold_out) ###

  note=local_time+s1

  print(s1)

  

  

# 黃金金價買價  加入每一秒自動爬蟲一次

import time

import urllib.request as request

from bs4 import BeautifulSoup as sp

import requests

local_time = time.ctime(time.time())

j=0

while j==0:

url="https://rate.bot.com.tw/gold?Lang=zh-TW" ###

with request.urlopen(url) as response:

  data=response.read().decode("utf-8")

root=sp(data,"html.parser")

gold_in=(root.find_all("td")[5].text.replace("回售","").strip()) ###

gold_out=(root.find_all("td")[2].text.replace("買進","").strip()) ###

s1=("\nGold"+"\n銀行買進: "+gold_in+"\n銀行賣出: "+gold_out) ###

note=local_time+s1

print(s1)

time.sleep(1)

每秒更新買進和回售價格
