硒python绑定是否需要firefox

嗨,我刚刚下载并安装了selenium,但是我无法确定如何使其正常工作,我正在使用以下示例进行测试….

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()         #this is where I hit the error
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.send_keys("selenium")
elem.send_keys(Keys.RETURN)
assert "Google" in driver.title
driver.close()

我的计算机上没有安装firefox,这就是为什么它给我一个错误？
这是我尝试运行时收到的错误输出

Traceback (most recent call last):

    driver = webdriver.Firefox()

解决方法:

下一行启动Firefox浏览器,因此是的,它需要安装Firefox.

driver = webdriver.Firefox()  

如果您没有安装Firefox,则可以改用其他浏览器：

webdriver.Opera
webdriver.Ie
webdriver.Chrome
...
