python selenium

Question

selennium 用论坛的这个 [](https://blog.csdn.net/chuhe163/article/details/108422

```python
driver.get("https://www.baidu.com")
from time import sleep
sleep(5)
print(driver)
print(driver.title)
sleep(5)

print(driver.find_element(By.ID,'su'))

```628 ) 就会报错，单存查询标题可以，只要查询ID就报错，提示selenium.common.exceptions.InvalidArgumentException: Message: using parameter value 'id' is not a valid value

Answer 1

这个错误是因为在使用 find_element 方法时，参数 By.ID 应该是 By.ID 而不是 'id'。正确的代码demo：

from selenium import webdriver
from selenium.webdriver.common.by import By
from time import sleep

driver = webdriver.Chrome()
driver.get("https://www.baidu.com")
sleep(5)
print(driver.title)
sleep(5)
print(driver.find_element(By.ID, 'su'))
