Unable to grab div tag in Beautiful Soup in Python,

I'm trying to download all the pokemon images available on the official website. The reason I'm doing this is because I want high quality images. Following is the code that I wrote.

from bs4 import BeautifulSoup as bs4
import requests
request = requests.get('https://www.pokemon.com/us/pokedex/')
soup = bs4(request.text, 'html')
print(soup.findAll('div',{'class':'container       pokedex'}))

Output is

[]

Is there something that I'm doing wrong? Also, is it legal to scrape from official website? Is there any tag or something that tells this?. Thanks

P.S: I'm new to BS and html.

This could've been done much easier had you inspected the network tab first:

import time
import requests


endpoint = "https://www.pokemon.com/us/api/pokedex/kalos"
# contains all metadata
data = requests.get(endpoint).json()

# collect keys needed to save the picture
items = [{"name": item["name"], "link": item["ThumbnailImage"]} for item in data]

# remove duplicates
d = [dict(t) for t in {tuple(d.items()) for d in items}]
assert len(d) == 893


for pokemon in d:
    response = requests.get(pokemon["link"])
    time.sleep(1)
    with open(f"{pokemon['name']}.png", "wb") as f:
        f.write(response.content)

The images are loaded dynamically, so you have to use selenium to scrape them. Here is the full code to do it:

from selenium import webdriver
import time
import requests

driver = webdriver.Chrome()

driver.get('https://www.pokemon.com/us/pokedex/')

time.sleep(4)

li_tags = driver.find_elements_by_class_name('animating')[:-3]

li_num = 1

for li in li_tags:
    img_link = li.find_element_by_xpath('.//img').get_attribute('src')
    name = li.find_element_by_xpath(f'/html/body/div[4]/section[5]/ul/li[{li_num}]/div/h5').text

    r = requests.get(img_link)
    
    with open(f"D:\\{name}.png", "wb") as f:
        f.write(r.content)

    li_num += 1

driver.close()

Output:

12 pokemon images. Here are the first 2 images:

Image 1:

Image 2:

Plus, what I noticed was that there was a load more button at the bottom of the page. When clicked, it loads more images. We have to keep scrolling down after clicking the load more button to load more images. If I am not wrong, there is a total of 893 images on the website. In order to scrape all 893 images, you can use this code:

from selenium import webdriver
import time
import requests

driver = webdriver.Chrome()

driver.get('https://www.pokemon.com/us/pokedex/')

time.sleep(3)

load_more = driver.find_element_by_xpath('//*[@id="loadMore"]')

driver.execute_script("arguments[0].click();",load_more)

lenOfPage = driver.execute_script("window.scrollTo(0, document.body.scrollHeight);var lenOfPage=document.body.scrollHeight;return lenOfPage;")
match=False
while(match==False):
        lastCount = lenOfPage
        time.sleep(1.5)
        lenOfPage = driver.execute_script("window.scrollTo(0, document.body.scrollHeight);var lenOfPage=document.body.scrollHeight;return lenOfPage;")
        if lastCount==lenOfPage:
            match=True

li_tags = driver.find_elements_by_class_name('animating')[:-3]

li_num = 1

for li in li_tags:
    img_link = li.find_element_by_xpath('.//img').get_attribute('src')
    name = li.find_element_by_xpath(f'/html/body/div[4]/section[5]/ul/li[{li_num}]/div/h5').text

    r = requests.get(img_link)
    
    with open(f"D:\\{name}.png", "wb") as f:
        f.write(r.content)

    li_num += 1

driver.close()
