Python Selenium - I can't run the while loop

Question

I just started python. I want to write a loop containing bot using Selenium. I want to login to a site. I send my number and password. The page refreshes when there is density on the server. Number and password sections are being cleaned. I want it to try to login with the same number and password until I log in to the system. If I enter text in the number section, the loop works, but I need to enter a number.

from selenium import webdriver
import time
browser = webdriver.Chrome()
browser.get("https://www.*****.com")
time.sleep(1)

loginbutton = browser.find_element_by_name('login')
no = browser.find_element_by_name('no')
password = browser.find_element_by_name('pass')

while True:
    no.send_keys("160210051")
    password.send_keys("example")
    time.sleep(1)

    loginbutton.click()
    no.clear()
    password.clear()
    continue

python shell, error descripton

@MatthewGaiser my problem is no.sendkeys does not send my number when the loop returns. — Redhill, Jan 31 '20 at 09:42

Add a sleep in the while loop

Clicking login likely changes the page so that the number and password fields no longer exist. You need to have the while pause for a period of time between attempts.

I add time.sleep(3) before the continue line, but again I get the same error. – Redhill Jan 31 '20 at 10:21
and the name of the fields does not change. still login, no and pass. – Redhill Jan 31 '20 at 10:34

I found finding elements in the while loop and it worked. The elements in the past are deleted after the page is refreshed. Thanks everyone.
