原先代码：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC


browser= webdriver.Chrome()
wait=WebDriverWait(browser,10)

def search():


    browser.get('https://www.taobao.com')
    input=wait.until(
        EC.presence_of_all_elements_located((By.CSS_SELECTOR, '#q'))
    )
    print (input)
    print (type(input))

    submit=wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR,'#J_TSearchForm > div.search-button > button')))
    input.send_keys('美食')
    submit.click()


def main():
    search()

if __name__=='__main__':
    main()

解决办法：

改成input[0].send_keys('美食')

list 不能调用 send_keys,那我就调用list[0] 取第一个值调用即可?
