Selenium Webdriver for Python traceback errors

I'm trying selenium webdriver for the first time. I've update to Python 3.6 and I reinstalled selenium as well. Trying to open a basic webpage has gone wrong already. Here is the code:

from selenium import webdriver
driver = webdriver.Firefox()
driver.get("http://www.python.org")

It's very basic yet it still isn't working. It's throwing a few errors that are beyond my skill of interpreting. Of course, I tried googling the issue and nothing seemed to help. I'd appreciate any input. These are the errors:

Traceback (most recent call last):
  File "C:\Python36\lib\site-packages\selenium\webdriver\common\service.py", line 74, in start
    stdout=self.log_file, stderr=self.log_file)
  File "C:\Python36\lib\subprocess.py", line 707, in __init__restore_signals, start_new_session)
  File "C:\Python36\lib\subprocess.py", line 990, in _execute_child
startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:/Users/Will Pickard/PycharmProjects/Basics/Webdriver.py", line 3, in <module>
    driver = webdriver.Firefox()

self.service.start()
  File "C:\Python36\lib\site-packages\selenium\webdriver\common\service.py", line 81, in start
os.path.basename(self.path), self.start_error_message)

You would have to install geckodriver ( for gecko browsers like firefox after v47 ) or chromedriver ( for chrome browser). Once installed, you should be able to execute code using below mentioned configuration.

You can set DesiredCapabilities as FIREFOX and point to driver binary file. You should be able to configure driver with these capabilities and retrieve desired page.

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True
firefox_capabilities['binary'] = '/usr/local/bin/geckodriver'

driver = webdriver.Firefox(capabilities=firefox_capabilities)
driver.get("http://www.python.org")

Alternatively, if you are not sure that newer version of Firefox is being used, then you can do something like this without setting DesiredCapabilities:

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

driver = webdriver.Firefox(firefox_binary=FirefoxBinary('/usr/local/bin/geckodriver'))
driver.get("http://www.python.org")

Since a couple of versions ago, Selenium stopped providing native support for Firefox, and now relies on using an external browser driver for control. Download the available gecko webdriver and use the following code:

from selenium import webdriver
ff = "/path/to/geckodriver"
driver = webdriver.Firefox(executable_path=ff)
