Dear Programmers, Thank you for your responses. I have installed 'Beautiful
Soup' and I have the 'Getting Started in Beautiful Soup' book, but can't seem
to make any progress with it, I am too thick to make much use of it. I was
hoping I could scrape specified stuff off Web pages without using it. I have
installed 'Requests' also, is there any code I can use that you can suggest
that can access the sort of Web page values that I have referred to ? such as
odds, names of runners, stuff like that off the 'inspect element' or 'source'
htaml pages, on www.Racingpost.com.
