Just beginning with Selenium

[JLogan3o13]

I have used Selenium in other languages, just beginning to look at it in python. I am curious if anyone else has run into this issue; or if I am missing something stupid simple.

Simple code:

from selenium import  webdriver

browser = webdriver.Chrome()
print(type(browser))

returns an error:

selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/...river/home

Even though the chromedriver.exe (the version that correlates to my Chrome version) is in PATH. If I just click Start Run, I can launch it fine as just chromedriver, so I know it is being found in the Path.

Edit: I should clarify, it works if I point it at the chromedriver, like so:

from selenium import webdriver

driver = webdriver.Chrome('PathTO\\chromedriver.exe')  # Optional argument, if not specified will search path.
driver.get('http://www.google.com/');

Just don't understand why I need to specify like that when it is in the environment variable.
