I have searched a lot but haven't found a good answer on how to use BeautifulSoup and urllib to use a src link and download the image when it is without an extension, for example, the image for the Facebook app icon @ https://play.google.com/store/apps/details?id=com.facebook.katana is https://lh3.googleusercontent.com/ZZPdzvlpK9r_Df9C3M7j1rNRi7hhHRvPhlklJ3lfi5jk86Jd1s0Y5wcQ1QgbVaAP5Q=w300-rw - without an extension.
What library or method should I be using to download such images?
You can get the image using the img tag using the class name and the src attribute:
import requests
import urllib
r = requests.get("https://play.google.com/store/apps/details?id=com.facebook.katana")
from bs4 import BeautifulSoup
soup = BeautifulSoup(r.content)
img = soup.find("img",{"class":"cover-image"})["src"]
urllib.urlretrieve(img,"fb.jpg")
