ربات واتساپ

سلام .

من کد ربات واتساپ رو نوشتم ولی این ارور میده :

AttributeError: 'list' object has no attribute 'send_keys'

کد من هم این هستش:
from selenium import webdriver

driver = webdriver.Chrome('/home/amirhossein/python/selenium/chromedriver')
driver.get('https://web.whatsapp.com')

msg = input('whats your massage? : ')
num = int(input('how many time i send massage? : '))
name = input ('Type names :')
names = name.split(",")


for i in  names:
   user = driver.find_element_by_xpath(f'//span[@title = "{i}"]')
   user.click()
   msg2 = driver.find_elements_by_xpath('//*[@id="main"]/footer/div[1]/div[2]/div/div[2]')
   print(msg2)
   for x in range (num):
       msg2.send_keys(msg)
       driver.find_element_by_class_name('_1JNuk').click()
