How to put two "while" loops together in this case?

Question

I want to set max_chapter and do functions until chapter number reaches the max_chapter . Then, book number increased by 1 and go through the same function until the chapter number reaches the max_chapter .

For example, Book 1 - Chapter 1~20, the Book turns out to be Book 2 and do functions Book 2 - Chapter 1~20,... and so on.

Here is a part of my code that I have the question about:

import requests
from bs4 import BeautifulSoup
import operator

def start(max_book):
    word_list = []
    book = 1
    chapter = 1
    while book <= max_book:
        url = ('http://www.holybible.or.kr/B_NIV/cgi/bibleftxt.php?VR=NIV&VL='
               + str(book) + '&CN=' + str(chapter) + '&CV=99')
        while chapter <= 1:
            source_code = requests.get(url).text
            soup = BeautifulSoup(source_code, "html.parser")
            for bible_text in soup.findAll('font', {'class': 'tk4l'}):
                content = bible_text.get_text()
                words = content.lower().split()
                for each_word in words:
                    word_list.append(each_word)
            chapter += 1
        else:
            book += 1
    print(word_list)
start(1)

Answer 1

IIUC , you need to read first 20 chapters from each book.

def Readchapters(max_books,max_chapters):
    book=1
    chapter=1
    while book <= max_books:

        while chapter<=max_chapters:
             print "reading book :",book ,"Chapter : ",chapter
             url = 'http://www.holybible.or.kr/B_NIV/cgi/bibleftxt.php?VR=NIV&VL={}&CN={}&CV=99'.format(book, chapter)
             source_code = requests.get(url).text
             soup = BeautifulSoup(source_code, "html.parser")
             '''
             #do your scraping here
             ................................
             ................................
             '''       
             chapter+=1 #move to next chapter
        book += 1 #move to next book
        chapter=1 #reset the chapter back
Readchapters(2,20)

output

Answer 2

So, I think the str(chapter) and str(book) both should increase in order. no?

You simply just need to include the construction of the url inside the inner while loop to ensure that the url is updated with the new chapter number.

while book <= max_book:
    while chapter <= 1:
        url = 'http://www.holybible.or.kr/B_NIV/cgi/bibleftxt.php?VR=NIV&VL={}&CN={}&CV=99'.format(book, chapter)
