[Tutor] Problem on handling if statement

[Crusier]

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
