Searching Google with Selenium and Python
提问by dimensive
I am not able to do a simple google search through Selenium, although I believe I am doing it correctly. I attempted to follow the Selenium documentation, but I believe the issue might be caused by an improper install of python or selenium. I have little python knowledge. Here is my code:
我无法通过 Selenium 进行简单的谷歌搜索，但我相信我做得对。我试图遵循 Selenium 文档，但我认为该问题可能是由 python 或 selenium 安装不当引起的。我对python的了解很少。这是我的代码：
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.Firefox()
browser.get('http://www.google.com')
try:
element = WebDriverWait(browser, 10).until(EC.presence_of_element_located((By.ID, "gbqfq")))
finally:
browser.quit()
search = browser.find_element_by_name('q')
search.send_keys("google search through python")
This is what terminal outputs.
这就是终端输出的内容。

Your finallyblock will be executed whether there has been an exception or not. So browser.quit()is always executed.
finally无论是否有异常，你的 块都会被执行。所以 browser.quit()总是被执行。
If you want to just search this script will do it for you.
如果您只想搜索此脚本，它将为您完成。
import time
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
from selenium.webdriver.common.keys import Keys
browser = webdriver.Firefox()
browser.get('http://www.google.com')
search = browser.find_element_by_name('q')
search.send_keys("google search through python")
search.send_keys(Keys.RETURN) # hit return after you enter search text
time.sleep(5) # sleep for 5 seconds so you can see the results
browser.quit()
The selenium docson `waits.

driver.quit()terminates the session at that point. Try this:
driver.quit()在该点终止会话。尝试这个：
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.Firefox()
browser.get('http://www.google.com')
WebDriverWait(browser, 10).until(EC.presence_of_element_located((By.ID, "gbqfq")))
search = browser.find_element_by_name('q')
search.send_keys("google search through python")
browser.quit()
You mention that you have little python knowledge. It might be a good idea to either pick a language that you are already familiar with, or first got through some python tutorials to get yourself familiar with it.
你提到你对 Python 的了解很少。选择一种您已经熟悉的语言，或者先通过一些 Python 教程来熟悉它可能是一个好主意。
