Python Requests ConnectionErrorr [11001] getaddrinfo failed

Question

I'm making a stock index webscraper using beautifulsoup and requests but I can't figure out what's blocking the connection.

Here's my code:

from bs4 import BeautifulSoup
import requests


def scraper(link):
    response = requests.get(link, verify=False)
    soup = BeautifulSoup(response.content, 'html.parser')
    company = soup.find(class_="D(ib) ").get_text()
    response.close()
    return company


def main():
    ticker = input("Input stock ticker symbol:")
    site = ("http://finace.yahoo.com/quote/" + ticker.upper().strip())
    data = scraper(site)
    print(data)


main()

And Here's the exception:

C:\Python37-32\python.exe C:\Users\lucas\CS\Final_Project\Stock_Index_Scraper.py

Answer 1

The url address that you are calling contains a typo http://finace.yahoo.com/quote/ -> http://finaNce.yahoo.com/quote/

As a rule of thumb, whenever your scraper behaves in an unexpected way, it is always recommended to run the scenario in a browser and/or curl command line to debug any connection/javascript issues.
