I am executing the following python program, and getting error mentioned "'geckodriver' executable needs to be in PATH. "

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

driver = webdriver.Firefox()
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No result found." not in driver.page_source
driver.close()

Error:

Download the proper geckodriver depending upon your operating system and System Architecture from the url here - geckodriver

Now follow the below steps -
Extract the geckodriver file from the downloaded zip file. Now depending upon your operating system do the following.

For Linux system :

Open terminal and login as root user. copy/move the extracted geckodriver to bin direcctory.
In my case I moved the file to /usr/bin directory. Because the driver finds geckodriver binary in '/usr/bin' path and the problem is solved now.

To move the file inside bin directory use command like -

$mv 'geckodriver binary source path' 'destination path'
destination path should be the binary folder path as per user system.

For Windows System :
Just execute the the extracted geckodriver binary file.
