Python requests why is the code not working?

Question

Python

import requests
from bs4 import BeautifulSoup
from fake_useragent import UserAgent

url = "https://www.google.com/search?q=%D0%B4%D0%BE%D0%BB%D0%BB%D0%B0%D1%80&oq=%D0%B4%D0%BE%D0%BB%D0%BB%D0%B0%D1%80&aqs=chrome.0.69i59j0i67i131i433j0i67i433j0i67j0i67i433j46i433i512j0i67j0i433i512l2j0i512.6063j0j1&sourceid=chrome&ie=UTF-8"
gd = UserAgent().chrome
print(gd)
response = requests.get(url, headers={'User-Agent': gd})
print(response.status_code)
soup = BeautifulSoup(response.text, "lxml")
print(soup.find("span", {"class": "SwHCTb"}).text)

Gives an error message:

AttributeError: 'NoneType' object has no attribute 'text'

Why doesn't the code work?! All code seems to be correct. Plz tell me what is the problem.
If that site is the dollar rate.

Answer 1

If find() can't find anything, it returns None:
print(soup.find("nosuchtag"))
# None

from here

Answer 2

Content is generated via js, use selenium

Answer 3

You can use this Xpath

//span[text()='Российский рубль']/preceding-sibling::span

UPD

import requests
from fake_useragent import UserAgent
from lxml import etree

url = "https://www.google.com/search?q=%D0%B4%D0%BE%D0%BB%D0%BB%D0%B0%D1%80&oq=" \
      "%D0%B4%D0%BE%D0%BB%D0%BB%D0%B0%D1%80&aqs=chrome.0.69i59j0i67i131i433j0i6" \
      "7i433j0i67j0i67i433j46i433i512j0i67j0i433i512l2j0i512.6063j0j1&sourceid=chrome&ie=UTF-8"
gd = UserAgent().chrome
response = requests.get(url, headers={'User-Agent': gd})

htmlparser = etree.HTMLParser()
tree = etree.fromstring(response.text, htmlparser)

result = tree.xpath("//div[contains(text(),'Российский рубль')]")
price = result[0].text.split()[0]
print(f'Стоимость доллара: {price} руб.')

OUT

Стоимость доллара: 72,75
