无法在 Selenium Python 中编写循环

Question

我无法在 selenium python 中编写循环，我正在尝试制作一个机器人来编写产品描述。对于第一个产品，循环工作成功，但是当出现第二个产品时，它会出现回溯错误

productList = driver.find_element(By.XPATH, '//*[@id="product_form"]/table/tbody').find_elements(By.CLASS_NAME, "no-padding")

for index in range(len(productList)):
    productList = driver.find_element(By.ID, "product_form").find_elements(By.CLASS_NAME, "no-padding")                           
    productList[index].find_element(By.TAG_NAME, 'a').click()
    time.sleep(4)
    driver.switch_to.frame('content_ifr')
    driver.find_element(By.TAG_NAME, "p").send_keys("TEST")
    time.sleep(3)
    driver.back()
    time.sleep(5)

Traceback (most recent call last):

这是在 Selenium 上进行循环的基本代码，进入更改页面的元素，返回并继续迭代

小心使用相同的变量名

productList = find_elements(...) #list

for index in range(len(productList)):

    #Do your work stuff
    .click()

    #Go BACK
    .back()


    #Get list again at end but inside loop to dont get error element changed in DOOM, same line befor start loop
    productList = find_elements(...) #list
