That setup work fine with a for loop to generate url's.

start = 1
stop = 5
for page in range(start, stop):
    url = 'https://10.10.10.0/vmrest/users?rowsPerPage=2000&pageNumber={}'.format(page)
    print(url)

Output:
https://10.10.10.0/vmrest/users?rowsPerPage=2000&pageNumber=1
https://10.10.10.0/vmrest/users?rowsPerPage=2000&pageNumber=2
https://10.10.10.0/vmrest/users?rowsPerPage=2000&pageNumber=3
https://10.10.10.0/vmrest/users?rowsPerPage=2000&pageNumber=4

Has a similar example in Web-scraping part-2,also a demo with concurrent.futures to speed it up.

Ok great! Thank you.

Let me ask you, will I have to have a separate "soup" variable for each URL or can I cram all the pages into one variable? So when it visits each page, I want it to add on to the last page it put into the soup variable.

You pass url to Requests and BS in same loop.
Example:

start = 1
stop = 5
for page in range(start, stop):
    url = 'https://10.10.10.0/vmrest/users?rowsPerPage=2000&pageNumber={}'.format(page)
    url_get = requests.get(url)
    soup = BeautifulSoup(url_get.content, 'lxml')
    foo = soup.find('do scraping')
    # save foo

Quote:or can I cram all the pages into one variable?

Not variable but a data structure like eg list,you can collect urls.

from pprint import pprint

urls = []
start = 1
stop = 5
for page in range(start, stop):
    url = 'https://10.10.10.0/vmrest/users?rowsPerPage=2000&pageNumber={}'.format(page)
    urls.append(url)

pprint(urls)

Output:
['https://10.10.10.0/vmrest/users?rowsPerPage=2000&pageNumber=1',
 'https://10.10.10.0/vmrest/users?rowsPerPage=2000&pageNumber=2',
 'https://10.10.10.0/vmrest/users?rowsPerPage=2000&pageNumber=3',
 'https://10.10.10.0/vmrest/users?rowsPerPage=2000&pageNumber=4']

ok...so far I have this (below). I need to take my soup parsing data (alias and dtmf) and put it into a file, a .CSV file with a date time stamp in the file name instead of printing it to the screen.

import requests
import urllib3
urllib3.disable_warnings()
import lxml
from bs4 import BeautifulSoup

page = 1

while page < 6:
    url = 'https://10.10.10.1/vmrest/users?rowsPerPage=2000&pageNumber=' + str(page)
    request_page = requests.get(url, verify=False, auth=('User', 'Pass'))
    soup = BeautifulSoup(request_page.text, 'lxml')
    alias = soup.find_all('alias')
    dtmf = soup.find_all('dtmfaccessid')

    for i in range(0, len(alias)):
        print(alias[i].get_text(),end=' ')
        print(dtmf[i].get_text())

    page += 1

Will check out your tutorial too. Thanks for the help.
