The whole book is based on urlib library.

It's not based on urllib,it's used to read source code of web-site.
Requests is of course now the recommend way to do it.

Page 20,if i rewrite to use Request.
In bs4 need also to specify a parser to use,recommended is to use lxml as parser.

from urllib.request import urlopen
from bs4 import BeautifulSoup

html = urlopen("http://www.pythonscraping.com/pages/page3.html")
bsObj = BeautifulSoup(html)
for child in bsObj.find("table",{"id":"giftList"}).children:
    print(child)

With Requests and lxml as parser.

import requests
from bs4 import BeautifulSoup

html = requests.get("http://www.pythonscraping.com/pages/page3.html")
soup = BeautifulSoup(html.content, 'lxml')
for child in soup.find("table",{"id":"giftList"}).children:
    print(child)

Now you know how urllib.request import urlopen can be replaced bye Requests,
this apply to over 90% of example in book.
The parsing with BeautifulSoup is okay in book.
