Answer

There is no such element with class form in your page. Also you can send keys only to a input element and not a form element.

This should work

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium import webdriver


options = Options()

options.add_experimental_option("detach", True)
d = webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=options)

d.get('https://elzero.org/')
d.find_element(By.ID, "search").send_keys('python')

Additionaly you can send ENTER key to search the token.

d.find_element(By.ID, "search").send_keys(Keys.ENTER)
