Create Cricket Score API using Web Scrapping in Flask

  • Last Updated : 14 Sep, 2021

Cricket is one of the famous outdoor sport played worldwide. There are very few APIs providing live scoreboards and none of them are free to use. Using any of the scoreboards available we can create API for ourselves. This method not only works for Cricket Scoreboard but also for any information available online. Following is the flow in which this blog would guide to create an API and deploy it. 

  • Setting up the App Directory
  • Web Scrape data from NDTV Sports.
    • Beautiful Soup in Python would be used.
  • Create an API.
    • Flask would be used.
  • Heroku would be used for deployment,

Setting up the App Directory

Step 1: Create a Folder (eg. CricGFG).

Step 2: Set up the virtual environment. Here we create an environment .env

python -m venv .env

Step 3: Activate the environment.

.env\Scripts\activate



Getting the Data

Step 1: In Python, we have Beautiful Soup which is a library to pull out data from HTML files. To install Beautiful Soup, run a simple command;

pip install beautifulsoup4

Similarly, install the Requests module of Python.

pip install requests

We would use the NDTV Sports Cricket Scorecard to fetch the data. 

Step 3: Following are the steps for Scraping data from the Web Page. To get the HTML text from the web page;

html_text = requests.get(‘https://sports.ndtv.com/cricket/live-scores’).text

To represent the parsed object as a whole we use the BeautifulSoup object,

soup = BeautifulSoup(html_text, "html.parser")

Note: It is recommended to run and check the code after each step to know about the difference and thoroughly understand the concepts.



Example:

Python




from bs4 import BeautifulSoup
import requests
  
html_text = requests.get('https://sports.ndtv.com/cricket/live-scores').text
soup = BeautifulSoup(html_text, "html.parser")
print(soup)

We will further find all the required divs and other tags with their respective classes.

Python




from bs4 import BeautifulSoup
import requests
  
html_text = requests.get('https://sports.ndtv.com/cricket/live-scores').text
soup = BeautifulSoup(html_text, "html.parser")
sect = soup.find_all('div', class_='sp-scr_wrp')
section = sect[0]
description = section.find('span', class_='description').text
location = section.find('span', class_='location').text
current = section.find('div', class_='scr_dt-red').text
    section.find('a', class_='scr_ful-sbr-txt').get('href')

The next section of the code has our data that is our result. If for any of the reasons that code is not present in the HTML file, it would lead to an error, so including that part in a try and except block.

Complete Code:

Python3




from bs4 import BeautifulSoup
import requests
  
html_text = requests.get('https://sports.ndtv.com/cricket/live-scores').text
soup = BeautifulSoup(html_text, "html.parser")
sect = soup.find_all('div', class_='sp-scr_wrp ind-hig_crd vevent')
  
section = sect[0]
description = section.find('span', class_='description').text
location = section.find('span', class_='location').text
current = section.find('div', class_='scr_dt-red').text
link = "https://sports.ndtv.com/" + section.find(
    'a', class_='scr_ful-sbr-txt').get('href')
  
try:
    status = section.find_all('div', class_="scr_dt-red")[1].text
    block = section.find_all('div', class_='scr_tm-wrp')
    team1_block = block[0]
    team1_name = team1_block.find('div', class_='scr_tm-nm').text
    team1_score = team1_block.find('span', class_='scr_tm-run').text
    team2_block = block[1]
    team2_name = team2_block.find('div', class_='scr_tm-nm').text
    team2_score = team2_block.find('span', class_='scr_tm-run').text
    print(description)
    print(location)
    print(status)
    print(current)
    print(team1_name.strip())
    print(team1_score.strip())
    print(team2_name.strip())
    print(team2_score.strip())
    print(link)
except:
    print("Data not available")

Output:

Live score England vs India 3rd Test,Pataudi Trophy, 2021

Headingley, Leeds



England lead by 223 runs

Day 2 | Post Tea Session

England

301/3 (96.0)

India

78

Creating the API

We will use Flask  which is a micro web framework written in Python. 

pip install Flask

Following is the starter code for our flask application.

Python3




# We import the Flask Class, an instance of 
# this class will be our WSGI appliction.
from flask import Flask
  
# We create an instance of this class. The first
# argument is the name of the application’s module 
# or package. __name__ is a convenient shortcut for
# this that is appropriate for most cases.This is
# needed so that Flask knows where to look for resources
# such as templates and static files.
app = Flask(__name__)
  
# We use the route() decorator to tell Flask what URL 
# should trigger our function.
@app.route('/')
def cricgfg():
    return "Welcome to CricGFG!"
  
# main driver function
if __name__ == "__main__":
    
    # run() method of Flask class runs the 
    # application on the local development server.
    app.run(debug=True)

Output:

Open localhost on your browser:

We would now add our code of Web Scrapping into this and some helper methods provided by Flask to properly return JSON data.

Understanding Jsonify

jsonify is a function in Flask. It serializes data to JavaScript Object Notation (JSON) format. Consider the following code:

Python3




from flask import Flask, jsonify
  
app = Flask(__name__)
  
@app.route('/')
def cricgfg():
    
    # Creating a dictionary with data to test jsonfiy.
    result = {
        "Description": "Live score England vs India 3rd Test,Pataudi \
        Trophy, 2021",
        "Location": "Headingley, Leeds",
        "Status": "England lead by 223 runs",
        "Current": "Day 2 | Post Tea Session",
        "Team A": "England",
        "Team A Score": "301/3 (96.0)",
        "Team B": "India",
        "Team B Score": "78",
        "Full Scoreboard": "https://sports.ndtv.com//cricket/live-scorecard\
        /england-vs-india-3rd-test-leeds-enin08252021199051",
        "Credits": "NDTV Sports"
    }
    return jsonify(result)
  
if __name__ == "__main__":
    app.run(debug=True)

Output:

Now it’s time to merge all our codes. Let’s Start!



Python3




import requests
from bs4 import BeautifulSoup
from flask import Flask, jsonify
  
app = Flask(__name__)
  
  
@app.route('/')
def cricgfg():
    html_text = requests.get('https://sports.ndtv.com/cricket/live-scores').text
    soup = BeautifulSoup(html_text, "html.parser")
    sect = soup.find_all('div', class_='sp-scr_wrp ind-hig_crd vevent')
  
    section = sect[0]
    description = section.find('span', class_='description').text
    location = section.find('span', class_='location').text
    current = section.find('div', class_='scr_dt-red').text
    link = "https://sports.ndtv.com/" + section.find(
    'a', class_='scr_ful-sbr-txt').get('href')
  
    try:
        status = section.find_all('div', class_="scr_dt-red")[1].text
        block = section.find_all('div', class_='scr_tm-wrp')
        team1_block = block[0]
        team1_name = team1_block.find('div', class_='scr_tm-nm').text
        team1_score = team1_block.find('span', class_='scr_tm-run').text
        team2_block = block[1]
        team2_name = team2_block.find('div', class_='scr_tm-nm').text
        team2_score = team2_block.find('span', class_='scr_tm-run').text
        result = {
            "Description": description,
            "Location": location,
            "Status": status,
            "Current": current,
            "Team A": team1_name,
            "Team A Score": team1_score,
            "Team B": team2_name,
            "Team B Score": team2_score,
            "Full Scoreboard": link,
            "Credits": "NDTV Sports"
        }
    except:
        pass
    return jsonify(result)
  
if __name__ == "__main__":
    app.run(debug=True)

Output in the Browser:

Here we have created our own Cricket API.

Deploying API on Heroku

Step 1: You need to create an account on Heroku.

Step 2: Install Git on your machine.

Step 3: Install Heroku on your machine.

Step 4: Login to your Heroku Account

heroku login

Step 5: Install gunicorn which is a pure-Python HTTP server for WSGI applications. It allows you to run any Python application concurrently by running multiple Python processes.

pip install gunicorn

Step 6: We need to create a procfile which is a text file in the root directory of our application, to explicitly declare what command should be executed to start our app.



web: gunicorn CricGFG:app

Step 7: We further create a requirements.txt file that includes all the necessary modules which Heroku needs to run our flask application.

pip freeze >> requirements.txt

Step 8: Create an app on Heroku, click here.

Step 9: We now initialize a git repository and add our files to it.

git init
git add .
git commit -m "Cricket API Completed"

Step 10: We will now direct Heroku towards our git repository.

heroku git:remote -a cricgfg

Step 11: We will now push our files on Heroku.

git push heroku master

Finally, our API is now available on https://cricgfg.herokuapp.com/
