python for loop insert number from range-CodePudding

I'm trying to scrape a web page with pagination.

Code:

from requests_html import _URL, HTMLSession
from bs4 import BeautifulSoup

for page in range(1,6):
    s = HTMLSession()
    url = 'https://www.lazada.com.ph/catalog/?q=laptop'
    url  = '&page={}'
    r=s.get(url.format(page))
    print(url)

Output:

https://www.lazada.com.ph/catalog/?q=laptop&page={}
https://www.lazada.com.ph/catalog/?q=laptop&page={}
https://www.lazada.com.ph/catalog/?q=laptop&page={}
https://www.lazada.com.ph/catalog/?q=laptop&page={}
https://www.lazada.com.ph/catalog/?q=laptop&page={}

Expectation:

https://www.lazada.com.ph/catalog/?q=laptop&page={1}
https://www.lazada.com.ph/catalog/?q=laptop&page={2}
https://www.lazada.com.ph/catalog/?q=laptop&page={3}
https://www.lazada.com.ph/catalog/?q=laptop&page={4}
https://www.lazada.com.ph/catalog/?q=laptop&page={5}

I'm still new and learning python, please help me to get the my expected result. Thanks in advance.

If your python version supports f strings...

from requests_html import _URL, HTMLSession
from bs4 import BeautifulSoup

for page in range(1,6):
    s = HTMLSession()
    url = f'https://www.lazada.com.ph/catalog/?q=laptop&page={page}'
    r = s.get(url)
    print(url)

CodePudding user response：

The url doesn't get modified, try:

from requests_html import _URL, HTMLSession
from bs4 import BeautifulSoup

for page in range(1,6):
    s = HTMLSession()
    url = 'https://www.lazada.com.ph/catalog/?q=laptop'
    url  = '&page={}'
    url = url.format(page)
    r = s.get(url)
    print(url)

Or even better:

from requests_html import _URL, HTMLSession
from bs4 import BeautifulSoup
for page in range(1,6):
    s = HTMLSession()
    url = 'https://www.lazada.com.ph/catalog/?q=laptop&page={}'.format(page)
    r = s.get(url)
    print(url)
