beautifulsoup - Scraper in Python gives "Access Denied"

Question

I'm trying to code a scraper in Python to get some info from a page. Like the title of the offers that appear on this page:
https://www.justdial.com/Panipat/Saree-Retailers/nct-10420585

By now I use this code :

import bs4
import requests

def extract_source(url):
    source=requests.get(url).text
    return source

def extract_data(source):
    soup=bs4.BeautifulSoup(source)
    names=soup.findAll('title')
    for i in names:
        print i

extract_data(extract_source('https://www.justdial.com/Panipat/Saree-Retailers/nct-10420585'))

But when I execute this code, it gives me an error:

<titlee> Access Denied</titlee>

What can I do to solve this?

As was mentioned in comments, you need to specify allowable user-agent and pass it as headers:

def extract_source(url):
    headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0'}
    source=requests.get(url, headers=headers).text
    return source
