python if does not equal with beautifulsoup and urllib

Here is yet another problem I am over thinking. I want the code to only print when the time that I scrape changes. All it does now is just keep printing the current price and never changes. What am I doing wrong?

import urllib.request
import bs4 as bs


while True:
    # Request Webpage
    url = 
urllib.request.urlopen('https://markets.businessinsider.com/index/realtime-chart/dow_jones').read()

    # Raw Webpage
    rawpage = bs.BeautifulSoup(url, 'lxml')

    price = rawpage.find_all('span', class_='push-data')[0]
    change = rawpage.find_all('span', class_='push-data')[1]
    currenttime = rawpage.find_all('span', class_='push-data')[3]
    new_time = ""

    if new_time != currenttime:
        print(price.text)
        print(change.text)
        print(currenttime.text)
