Question

我一直收到如下错误：

NameError：name＆＃39; By＆＃39;未定义

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？

Answer 1

你必须导入它

*, *::before, *::after {
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
}

.reply_placeholder {
  padding: 30px 30px 20px 65px; /* changed padding-left from 30 to 65px */

  position: absolute;
  bottom: 0;
  width: 100%;
  overflow: hidden;
  border-top: 1px solid #DDD;
}

.logo {
  position: absolute; /* new */
  top: 50%; /* new */
  left: 0; /* new */
  margin-top: -20px; /* new */

  background-image: url("http://placekitten.com/g/200/200");
  width: 50px;
  height: 50px;
  border-radius: 3px;
  border: 1px solid #dddddd;
  background-size: cover;
  background-position: center center;
  display: block; /* inline-block to block */
  margin-right: 10px;
}

.reply_placeholder input {
  display: block;
  width: 100%;
  height: 50px;
  float: right;
}
