Hi I just downloaded and installed selenium but, I can't figure out how to get it working I am using the following example as a test....

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()

I do not have firefox installed on my computer is this why it is giving me an error? this is the error output I get when I try and run it

Traceback (most recent call last):
  File "C:/Python27/test/helloworld.py", line 4, in <module>
    driver = webdriver.Firefox()
  File "C:\Python27\lib\site-packages\selenium-2.35.0-py2.7.egg\selenium\webdriver\firefox\webdriver.py", line 60, in __init__

以下行启动 Firefox 浏览器，所以是的，它需要安装 Firefox。

driver = webdriver.Firefox()

如果您没有安装 Firefox，您可以使用不同的浏览器：

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

看
