Python Selenium Webdriver(名称'by'未定义)

Question

我一直收到如下错误:

NameError:未定义名称"By"

代码

chrome_driver_path = r"C:\chromedriver.exe"
from selenium import webdriver
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait
browser = webdriver.Chrome(chrome_driver_path)
browser.delete_all_cookies()
browser.get("https://www.google.com/")
wait = WebDriverWait(browser, 10)
element = wait.until(EC.element_to_be_clickable((By.XPATH, '//*[@id="tsf"]/div[2]/div[3]/center/input[1]')))  

我的导入是否正确？

from selenium.webdriver.common.by import By

Answer 2
