By “shallow copying” it means the content of the dictionary is not copied by value, but just creating a new reference. >>> a = {1: [1,2,3]} >>> b = a.copy() >>> a, b ({1: [1, 2, 3]}, {1: [1, 2, 3]}) >>> a[1].append(4) >>> a, b ({1: [1, 2, 3, 4]}, {1: [1, 2, 3, …

Provide the meta tag name as the first argument to find(). Then, use keyword arguments to check the specific attributes: title = soup.find(“meta”, property=”og:title”) url = soup.find(“meta”, property=”og:url”) print(title[“content”] if title else “No meta title given”) print(url[“content”] if url else “No meta url given”) The if/else checks here would be optional if you know that …
