WebDriverException: Message: 'chromedriver' executable needs to be in PATH while setting UserAgent through Selenium Chromedriver python

Question

I'm a newbie in webscraping, I'm trying to modify my user agent using these lines :

from selenium import webdriver
chrome_path = r'C:\Users\Desktop\chromedriver_win32\chromedriver.exe'   
driver = webdriver.Chrome(chrome_path)
options = webdriver.ChromeOptions()
options.add_argument('user-agent = Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36')
driver = webdriver.Chrome(chrome_options=options)

The path in environment variable is ok but I keep having this error message:

File "C:\Users\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\common\service.py", line 76, in startstdin=PIPE)
File "C:\Users\AppData\Local\Programs\Python\Python36-32\lib\subprocess.py",line 709, in __init__restore_signals, start_new_session)
File "C:\Users\AppData\Local\Programs\Python\Python36-32\lib\subprocess.py",line 997, in _execute_child startupinfo).
During handling of the above exception, another exception occurred:
Traceback (most recent call last):

os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

Can you please help me fix this issue?

Solution

This error message...

selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH

...implies that the ChromeDriver was not found within the locations specified within PATH variable within Environment Variables.

Solution

You need to pass the Key executable_path along with the Value referring to the absolute path of the ChromeDriver along with the ChromeOptions object as an argument while initializing the WebDriver and WebBrowser as follows :

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument('user-agent = Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36')
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Users\Desktop\chromedriver_win32\chromedriver.exe')
driver.get('https://www.google.co.in')
