Dear All,
I am trying to do some web scraping. Attached below is my code:
from bs4 import BeautifulSoup
import requests
#string = str(0175, 0005, 1177)
url = "https://www.etnet.com.hk/www/eng/stocks/realtime/quote.php?code=0175"
def web_scraper(url):
response = requests.get(url)
html = response.content
soup = BeautifulSoup(html,"html.parser")
real_time_down = soup.find("span", attrs = {"class": "Price down2"})
real_time_up = soup.find("span", attrs = {"class": "Price up2"})
real_time_unchange = soup.find("span",attrs = {"class" :"Price unchange2"})
change_percent = soup.find("span", attrs = {"class" :"Change"})
if real_time_down == soup.find("span", attrs = {"class" : "Price
down2"}) or real_time_up == soup.find("span", attrs \
= {"class": "Price up2"}) or real_time_unchange ==
soup.find("span",{"class" : "Price unchange2"}) :
print(real_time_down)
print(real_time_up)
print(real_time_unchange)
print(change_percent.string)
else:
return None
web_scraper(url)
I have problem trying to get rid of None object. For example, if I put
in 1177 to the url, the real_price_down and the real_time_unchange
will become a None Object. I hope that the program will be able to
sort it out automatically and able to print out the string.
Please help. Thank you very much
Regards,
Henry
