Just noticed that was almost a year ago and I haven't done anything with Python since I'll try and take a look later as I could do with getting back into coding myself.

never used python, i'm still getting to gips with power querys in excel.
is it easy to learn for an old'en like me.

Code: Select all

import re
import requests
from bs4 import BeautifulSoup
from requests_html import HTMLSession

def extract_times(input):
    times_regex = re.compile(r'Best: (.....)sLast: (.....)s')
    best_times_regex = re.compile(r'Best: (.....)s')
    match = times_regex.search(input)
    best_match = best_times_regex.search(input)

    if match:
        if float(match.group(2)) < float(match.group(1)):
            return float(match.group(2))
        else:
            return round((float(match.group(1)) + float(match.group(2))) / 2, 2)

    return 100



def main():
    session = HTMLSession()
    baseUrl = "https://www.sportinglife.com"
    results = []
    res = requests.get("https://www.sportinglife.com/greyhounds/racecards")
    soup = BeautifulSoup(res.text, "html.parser")
    summary = list(filter(None, [link.find_parent('a', class_='') for link in soup.find_all('span', class_='gh-meeting-race-time')]))

    x = 0
    for tag in summary:
        link = tag.get('href')
        res = session.get(baseUrl + link)
        soup = BeautifulSoup(res.text, "html.parser")
        race = soup.find('h1').get_text()
        grade = soup.find(class_='gh-racecard-summary-race-class gh-racecard-summary-always-open').get_text()
        summary = soup.find_all(class_="gh-racing-runner-key-info-container")
        Runners = dict()

        for runner in summary:
            Trap = runner.find(class_="gh-racing-runner-cloth").get_text()
            Name = re.sub(r'\(.*\)', '', runner.find(class_="gh-racing-runner-greyhound-name").get_text())
            Average_time = extract_times(runner.find(class_="gh-racing-runner-greyhound-sub-info").get_text())
            Runners[Average_time] = Trap + '. ' + Name

        if bool(Runners) == True and ('OR' in grade or 'A' in grade):

            x = sorted(((k, v) for k, v in Runners.items()))

            if (x[1][0] - x[0][0]) >= 0.1:
                timeDiff = round((x[1][0] - x[0][0]), 2)
                results.append(race + ', ' + x[0][1] + ', class ' + grade + ', time difference ' + str(timeDiff))
    results.sort()
    file = open('dogs_1.txt', mode='w')
    for line in results: file.write(line+'\n')
    file.close()
    
main()

fixed the code and cleaned it a little bit. the results are now stored in a txt file.

Thanks, any idea why the old code had stopped working ?

can't quite remember well because i've worked on the code last summer. but i remember that the code wasn't retrieving any race link from the main page in the first place.

can you do a step by step guide on how to load it

can you do a step by step guide on how to load it

You'd need to have python installed on your PC and all the relevant libraries, from there it's no more than opening the file and pressing run.

https://www.python.org/downloads/release/python-391/ your OS needs to be above win 7

If you want to instal it I can take you from there

can you do a step by step guide on how to load it

1. if you don't have python installed, download the installer from here https://www.python.org/downloads/
2. during the installation, make sure to check the "Add to PATH" checkbox.
3. open notepad, paste the code and save the file with ".py" extension (<something>.py)
4. open Command Prompt and change the working directory to where you have your python script: cd <your directory>
5. run the python script: python <your filename>
if it doesn't work try with "python3". if that doesn't work either, you probably haven't added python to PATH
6. wait 1/2 min until the program finishes.
7. check the new txt file that has appeared in the folder where the script is. the file is overwritten every time you run the script.
And that's the quickest way to run a python code, just by the command line. No additional software.

Yes, I forgot to mention that you need to install requests and beautifulsoup4 libraries for the script to run. you can do that by typing "pip(or pip3) install beautifulsoup4, requests" command in the command prompt

Vlad you legend ... thanks
