Web Scraping Python using Google Chrome extension
Question: Hi I am a Python newbie and I am webscrapping a webpage.

I am using the Google Chrome Developer Extension to identify the class of the
objects I want to scrape. However, my code returns an empty array of results
whereas the screenshots clearly show that that those strings are in the HTML
code. [Chrome Developer](http://i.stack.imgur.com/0Xf87.png)

    
    
    import requests
    from bs4 import BeautifulSoup
    
        url = 'http://www.momondo.de/flightsearch/?Search=true&TripType=2&SegNo=2&SO0=BOS&SD0=LON&SDP0=07-09-2016&SO1=LON&SD1=BOS&SDP1=12-09-2016&AD=1&TK=ECO&DO=false&NA=false'
        html = requests.get(url)
        soup = BeautifulSoup(html.text,"lxml")
        x = soup.find_all("span", {"class":"value"})
        print(x)
        #pprint.pprint (soup.div)
    

I am very much appreciating your help!

Many thanks!

Make sure the data you are expecting is actually there. Use
`print(soup.prettify())` to see what was actually returned from the request.
Depending on how the site works, the data you are looking for may only exist
in the browser after the javascript is processed. You might also want to take
a look at [selenium](http://www.seleniumhq.org/)
