Getting Extension

[Harshil]

Hey! Friends.
Problem: How to get extension of the file from url or else anything using request or any module?
Another Problem: Can I Use To Split Files In Python And Download Them Using Threading?
Here Is The Code:

import requests
import threading
def download(url):
    r = requests.get(url, allow_redirects=True)

    response = requests.get(url, stream = True)

    text_file = open("data.html","wb")
    for chunk in response.iter_content(chunk_size=1024):
        text_file.write(chunk)
    #writing one chunk at a time to text file


    text_file.close()
t = threading.Thread(target=download,args=('https://youtu.be/zcywDfl7vJs',))
t.start()
