BeautifulSoup parser can't access html element

I am trying to scrape the hrefs of all the listings. I am fairly new to beautifulsoup and have done a bit of scraping before, but have done some scraping before. But I can't for the life of me extract. See below my code. the container has length zero when I run this script.

I try and select the price too (soup.findAll("span", {"class":"amount"}) , but it doesn't reflect. Any advice most welcome :)

import urllib.request
import urllib.parse
from bs4 import BeautifulSoup

url = 'https://www.takealot.com/computers/laptops-10130'   
headers = {}
headers['User-Agent'] = "Mozilla/5.0 (X11; Linux i686) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.27 Safari/537.17"
req = urllib.request.Request(url, headers=headers)
resp = urllib.request.urlopen(req)

respData = str(resp.read())

soup = BeautifulSoup(respData, 'html.parser')

container = soup.find_all("div", {"class": "p-data left"})

The page is rendered with JavaScript. There are several ways to render and scrape it.

I can scrape it with Selenium. First install Selenium:

sudo pip3 install selenium

Then get a driver https://sites.google.com/a/chromium.org/chromedriver/downloads you can use a headless version of chrome "Chrome Canary" if you are on Windows or Mac.

from bs4 import BeautifulSoup
from selenium import webdriver

browser = webdriver.Chrome()
url = ('https://www.takealot.com/computers/laptops-10130')
browser.get(url)
respData = browser.page_source
browser.quit()
soup = BeautifulSoup(respData, 'html.parser')
containers = soup.find_all("div", {"class": "p-data left"})
for container in containers:
    print(container.text)
    print(container.find("span", {"class": "amount"}).text)

Alternatively use PyQt5

from PyQt5.QtGui import *
from PyQt5.QtCore import *
from PyQt5.QtWebKit import *
from PyQt5.QtWebKitWidgets import QWebPage
from PyQt5.QtWidgets import QApplication
from bs4 import BeautifulSoup
import sys


class Render(QWebPage):
    def __init__(self, url):
        self.app = QApplication(sys.argv)
        QWebPage.__init__(self)
        self.loadFinished.connect(self._loadFinished)
        self.mainFrame().load(QUrl(url))
        self.app.exec_()

    def _loadFinished(self, result):
        self.frame = self.mainFrame()
        self.app.quit()

url = 'https://www.takealot.com/computers/laptops-10130'
r = Render(url)
respData = r.frame.toHtml()
soup = BeautifulSoup(respData, 'html.parser')
containers = soup.find_all("div", {"class": "p-data left"})
for container in containers:
    print (container.text)
    print (container.find("span", {"class":"amount"}).text)

Alternatively use dryscrape:

from bs4 import BeautifulSoup
import dryscrape

url = 'https://www.takealot.com/computers/laptops-10130'
session = dryscrape.Session()
session.visit(url)
respData = session.body()
soup = BeautifulSoup(respData, 'html.parser')
containers = soup.find_all("div", {"class": "p-data left"})
for container in containers:
    print(container.text)
    print(container.find("span", {"class": "amount"}).text)

Outputs in all cases:

However when testing with your URL I observed the results were not reproducible every time, occasionally I got no content in "containers" after the page had rendered.
