How to restart browser in selenium?

Question

Python

In general, I need to restart the browser in selenium, just restart. There is a for loop, and selenium is launched in it, at the next iteration I need to restart the browser, but with a different proxy, because the number of requests on the server is limited, I need to bypass this. Googled it - nothing works.
Here is the code

import sys
import config
from excel import Excel
import keyboard
import time
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from bs4 import BeautifulSoup

def cooldown(cooldown):
    for i in range(cooldown, 0, -1):
        print('Cooldown ends in {}'.format(i), end='')
        print('\r', end='')
        time.sleep(1)

for i in range(1, len(sys.argv)):
    if sys.argv[i] == '--help':
        print('1')
        sys.exit(0)

URL = sys.argv[1]
DEVICE = sys.argv[2] if sys.argv[2] == 'Desktop' or sys.argv[2] == 'desktop' or sys.argv[2] == 'mobile' or sys.argv[2] == 'Mobile' else sys.exit('Device is invalid. It\'s either "Desktop" or "Mobile"')

print('Url: {}\nDevice: {}'.format(URL, DEVICE))
