from flask import Flask, jsonify 
import requests 
import re 
from bs4 import BeautifulSoup as bs 

app = Flask(__name__)


#website url 
url = 'https://www.goodreturns.in/currency/world-currencies-vs-indian-rupee-inr.html'


#rate extracting regex
#regex  to fetch the currency name  
fetch_currency_name  = r'<td\swidth="250">[a-bA-Z0-9].*</td>'


#regex to fetch the rate
fetch_rate  = r'<span>[0-9]*\.[0-9]*</span>' 


#fetch data from the server
def fetch(url):
    #fetch the page and parse it using the bs4 
    page = requests.get(url)
    page_txt  = page.text

    currency = {}

    for i,j in zip(re.findall(fetch_currency_name, page_txt), re.findall(fetch_rate, page_txt)):
        currency[bs(i, 'html.parser').text] = bs(j, 'html.parser').text
    
    return currency
    
    

#main route 
@app.route('/', methods=['POST', 'GET'])
def main():
    return jsonify(fetch(url))


if __name__=='__main__':
    app.run()

Is it's leagal to fetch data from that URL? , can we use this commercial use?

@rajulapatisairam Web scraping is not illegal in itself, but when you are using it for commercial purposes, you have to look at the terms and conditions of the website in question.
